[7.x][ML] Add optional source filtering during data frame reindexing (#49690) (#49718)
This adds a `_source` setting under the `source` setting of a data
frame analytics config. The new `_source` is reusing the structure
of a `FetchSourceContext` like `analyzed_fields` does. Specifying
includes and excludes for source allows selecting which fields
will get reindexed and will be available in the destination index.

Closes #49531

Backport of #49690
