Improve dll plugin relation with webpackshims (#30129) (#31766)

* chore(NA): remove specific watch for x-pack webpackShims folder.

* chore(NA): remove xpack security plugin angular-ui-select webpackShim.

* chore(NA): bump ui-select version on x-pack to match the one used on oss kibana

* chore(NA): remove manual searching for webpackShim imports into the dll plugin. chore(NA): explicit avoid max dll compilations in all environments for the dll plugin. chore(NA): explicit throw an error and list all the not allowed modules bundled into the dll bundle.

* refact(NA): move ui related actions inside webpackShims to proper ui related files

* chore(NA): move angular ui dependencies from webpackShims to kibana core module.

* test(NA): enable xpack jest tests to be able to resolve plugins/xpack_main/*. refact(NA): rewrite code for the old xpack jquery flot webpackShim.

* refact(NA): use the already declared ui module get to list the dependencies for the kibana legacy core plugin.

* chore(NA): move angular ui requires to a better centralized place.

* refact(NA): rename areMaxCompilationsPerformed to assertMaxCompilations.

* refact(NA): remove unnecessary promise resolve on async function.

* refact(NA): remove unnecessary promise resolve on async function.

* refact(NA): apply changes according pr review.

* refact(NA): change from requires to imports in xpack_main plugin jquery flots.

* refact(NA): jquery flots missing statements.

* fix(na): linting problems.

* chore(na): re add jquery flot requires instead of imports.

* refact(NA): moving jquery flots from require to import. test(NA): fix mock for jquery_flot.

* feat(na): allow dynamic dll plugin public modules on dll bundle.

* feat(NA): step verification to not allow modules from xpack source.

* chore(NA): fix linting problems.
