This field mapper only lived in its own module so it could be licensed as x-pack basic. Now it can be moved to core, which matches its status as a core type.

Is this class for cases when _xpack/usage API is used in a mixed 7.12 and 7.13 nodes cluster, and this 7.13 node acts as a coordinating node and it needs to process the usage reply from 7.12 nodes?

Yes exactly. We took the same approach for runtime fields -- @javanna explained it nicely in the RuntimeFieldsFeatureSetUsage Javadoc.

This PR backports #68780 to move flattened fields to core.
It also removes flattened fields from xpack usage stats now that they live in
core. The usage stats were already removed in (#53076), but this PR was not
backported to avoid a breaking change on 7.x. We have now clarified that usage
stats updates are not considered breaking, so it is safe to backport this
change.
