ESQL: Clone ql for esql (#108773)
Part of https://github.com/elastic/elasticsearch/issues/106679

* Copy the `ql` project into a different project _just for esql_, call it `esql-core`.
* Make `esql` depend only on the latter.
* Fix `EsqlNodeSubclassTests`; I'm confused why this didn't bite us earlier.
* Update the warning regexes in some csv tests as the exceptions have other package names now.

**Note to reviewers:** Exclude the first commit when viewing the diff,
as that contains only the actual copying of `ql`. The remaining commits
are the actually meaningful ones. _The `build.gradle` files probably
require the most attention._

Note that in this example, the last value of the multi-valued field cannot be converted as an integer.
When this happens, the result is a *null* value. In this case a _Warning_ header is added to the response.
The header will provide information on the source of the failure:
`"Line 1:61: evaluation of [TO_INTEGER(long)] failed, treating result as null. Only first 20 failures recorded."`
A following header will contain the failure reason and the offending value:
`"org.elasticsearch.xpack.esql.core.InvalidArgumentException: [501379200000] out of [integer] range"`
