[ingest pipeline mgmt] Move to x-pack/platform/plugins/shared/ingest_pipelines (#204331)

## Summary

This PR aims at relocating some of the Kibana modules (plugins and
packages) into a new folder structure, according to the _Sustainable
Kibana Architecture_ initiative.

> [!IMPORTANT]
> * We kindly ask you to:
> * Manually fix the errors in the error section below (if there are
any).
> * Search for the `packages[\/\\]` and `plugins[\/\\]` patterns in the
source code (Babel and Eslint config files), and update them
appropriately.
> * Manually review
`.buildkite/scripts/pipelines/pull_request/pipeline.ts` to ensure that
any CI pipeline customizations continue to be correctly applied after
the changed path names
> * Review all of the updated files, specially the `.ts` and `.js` files
listed in the sections below, as some of them contain relative paths
that have been updated.
> * Think of potential impact of the move, including tooling and
configuration files that can be pointing to the relocated modules. E.g.:
>     * customised eslint rules
>     * docs pointing to source code

> [!NOTE]
> * This PR has been auto-generated.
> * Any manual contributions will be lost if the 'relocate' script is
re-run.
> * Try to obtain the missing reviews / approvals before applying manual
fixes, and/or keep your changes in a .patch / git stash.
> * Please use
[#sustainable_kibana_architecture](https://elastic.slack.com/archives/C07TCKTA22E)
Slack channel for feedback.
