Expanded `TEST_DIRECTORIES` to include new test paths for `platform` and
`solutions` groups.

### Module Grouping Logic:

[`packages/kbn-repo-source-classifier/src/group.ts`](diffhunk://#diff-ca1d6e73c75bc70f1f99a19fdc6cca66ca79dc290de32f222595aa7d0b5099b9R49-R52):
Updated `MODULE_GROUPING_BY_PATH` to include `x-pack/platform/test` and
`x-pack/solutions/*/test` directories under their respective groups with
appropriate visibility settings.

### Plugin Metadata Updates:

* Various plugin `kibana.jsonc` files under `x-pack/platform/test`:
Added `group` and `visibility` fields to ensure plugins are categorized
under the `platform` group with `private` visibility.
