[7.x] Add test for component templates updated after cluster restart (#58883) (#58914)

Browse Source 
This commit adds an integration test that component templates used to form a composite template can
still be updated after a cluster restart.

In #58643 an issue arose where mappings were causing problems because of the way we unwrap `_doc` in
template mappings. This was also related to the mappings being merged manually rather than using the
`MapperService` to do the merging. #58643 was fixed in 7.9 and master with the #58521 change, since
mappings now are read and digested by the actual mapper service.

This test passes for 7.x and master, and I intend to open a separate PR including this test for
7.8.1 along with a bug fix for #58643. This test is to ensure we don't have any regression in the
future.
