## Summary
This PR has breadth, but not depth. This adds 3 new `eslint` rules. The
first two protect against the use of code generated from strings (`eval`
and friends), which will not work client-side due to our CSP, and is not
something we wish to support server-side. The last rule aims to prevent
a subtle class of bugs, and to defend against a subset of prototype
pollution exploits:
- `no-new-func` to be compliant with our CSP, and to prevent code
execution from strings server-side:
https://eslint.org/docs/latest/rules/no-new-func
- `no-implied-eval` to be compliant with our CSP, and to prevent code
execution from strings server-side:
https://eslint.org/docs/latest/rules/no-implied-eval. Note that this
function implies that it prevents no-new-func, but I don't see [test
cases](https://github.com/eslint/eslint/blob/main/tests/lib/rules/no-implied-eval.js)
covering this behavior, so I think we should play it safe and enable
both rules.
- `no-prototype-builtins` to prevent accessing shadowed properties:
https://eslint.org/docs/latest/rules/no-prototype-builtins
In order to be compliant with `no-prototype-builtins`, I've migrated all
usages and variants of `Object.hasOwnProperty` to use the newer
[`Object.hasOwn`](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Object/hasOwn).
## Summary
Closes https://github.com/elastic/kibana/issues/174865
A bug was reported that noticed a difference between kbn-handlbars and
the original handlebars when it came to escaping nested values.
Additional checks have been added to verify whether escaping should be
performed.
## Testing
When reviewing the unit tests notice the permutations of
nested/un-nested inputs for each type of template(simple, helper, block)
with all values `noEscape` compiler option (default(false), false, true)
## Release Note
Fixed issue with `@kbn-handlebars` where nested inputs were not being
escaped properly

Previously a custom diff of the files inside the upstream `spec`
directory was kept up-to-date in this package `.patches` directory. This
process was very tedious and wasn't providing much value.
In this commit I've simplified the process tremendously and simply rely on
checking if there are any new commits upstream and then allow the
developer to manually check for relevant changes. This is something they
needed to do with the old system regardless. Here the code is just much
simpler.

## Dearest Reviewers 👋
I've been working on this branch with @mistic and @tylersmalley and
we're really confident in these changes. Additionally, this changes code
in nearly every package in the repo so we don't plan to wait for reviews
to get in before merging this. If you'd like to have a concern
addressed, please feel free to leave a review, but assuming that nobody
raises a blocker in the next 24 hours we plan to merge this EOD pacific
tomorrow, 12/22.
We'll be paying close attention to any issues this causes after merging
and work on getting those fixed ASAP. 🚀

The operations team is not confident that we'll have the time to achieve
what we originally set out to accomplish by moving to Bazel with the
time and resources we have available. We have also bought ourselves some
headroom with improvements to babel-register, optimizer caching, and
typescript project structure.
In order to make sure we deliver packages as quickly as possible (many
teams really want them), with a usable and familiar developer
experience, this PR removes Bazel for building packages in favor of
using the same JIT transpilation we use for plugins.
Additionally, packages now use `kbn_references` (again, just copying the
dx from plugins to packages).
Because of the complex relationships between packages/plugins and in
order to prepare ourselves for automatic dependency detection tools we
plan to use in the future, this PR also introduces a "TS Project Linter"
which will validate that every tsconfig.json file meets a few
requirements:
1. the chain of base config files extended by each config includes
`tsconfig.base.json` and not `tsconfig.json`
1. the `include` config is used, and not `files`
2. the `exclude` config includes `target/**/*`
3. the `outDir` compiler option is specified as `target/types`
1. none of these compiler options are specified: `declaration`,
`declarationMap`, `emitDeclarationOnly`, `skipLibCheck`, `target`,
`paths`
4. all references to other packages/plugins use their pkg id, ie:
```js
// valid
{
"kbn_references": ["@kbn/core"]
}
// not valid
{
"kbn_references": [{ "path": "../../../src/core/tsconfig.json" }]
}
```
5. only packages/plugins which are imported somewhere in the ts code are
listed in `kbn_references`
This linter is not only validating all of the tsconfig.json files, but
it also will fix these config files to deal with just about any
violation that can be produced. Just run `node scripts/ts_project_linter
--fix` locally to apply these fixes, or let CI take care of
automatically fixing things and pushing the changes to your PR.
> **Example:** [`64e93e5`
(#146212)](64e93e5806)
When I merged main into my PR it included a change which removed the
`@kbn/core-injected-metadata-browser` package. After resolving the
conflicts I missed a few tsconfig files which included references to the
now removed package. The TS Project Linter identified that these
references were removed from the code and pushed a change to the PR to
remove them from the tsconfig.json files.
## No bazel? Does that mean no packages??
Nope! We're still doing packages but we're pretty sure now that we won't
be using Bazel to accomplish the 'distributed caching' and 'change-based
tasks' portions of the packages project.
This PR actually makes packages much easier to work with and will be
followed up with the bundling benefits described by the original
packages RFC. Then we'll work on documentation and advocacy for using
packages for any and all new code.
We're pretty confident that implementing distributed caching and
change-based tasks will be necessary in the future, but because of
recent improvements in the repo we think we can live without them for
**at least** a year.
## Wait, there are still BUILD.bazel files in the repo
Yes, there are still three webpack bundles which are built by Bazel: the
`@kbn/ui-shared-deps-npm` DLL, `@kbn/ui-shared-deps-src` externals, and
the `@kbn/monaco` workers. These three webpack bundles are still created
during bootstrap and remotely cached using bazel. The next phase of this
project is to figure out how to get the package bundling features
described in the RFC with the current optimizer, and we expect these
bundles to go away then. Until then any package that is used in those
three bundles still needs to have a BUILD.bazel file so that they can be
referenced by the remaining webpack builds.

After adding support for decorators an `args` property has added to
`HelperOptions` (which is shared with decorators). To not leak this into
regular helpers and to align with the upstream handlebars, this PR
removes the `args` property from regular helpers so that it's only
visible to decorators.

Adds a new experimental Kibana setting called `csp.disableUnsafeEval` which will default to `false`. When set to `true`, it will remove `unsafe-eval` from our CSP.
Also introduces a new module called `@kbn/handlebars` which is a replacement for the official `handlebars` module used in the frontend. This new module is necessary in order to avoid calling `eval`/`new Function` from within `handlebars` which is not allowed once `unsafe-eval` is removed from our CSP.
The `@kbn/handlebars` module is simply an extension of the main `handlebars` module which adds a new compile function called `compileAST` (as an alternative to the regular `compile` function). This new function will not use code-generation from strings to compile the template but will instead generate an AST and return a render function with the same API as the function returned by the regular `compile` function.
This is a little bit slower method, but since this is only meant to be used client-side, the slowdown should not be an issue.
The following limitations exists when using `@kbn/handlebars`:
The Inline partials handlebars template feature is not supported.
Only the following compile options will be supported:
- `knownHelpers`
- `knownHelpersOnly`
- `strict`
- `assumeObjects`
- `noEscape`
- `data`
Only the following runtime options will be supported:
- `helpers`
- `blockParams`
- `data`
