* Decouple XContentBuilder from BytesReference
This commit handles the removal of all mentions of BytesReference from
XContentBuilder. This is needed so that we can completely decouple the XContent
code and move it into its own dependency.
This is the x-pack side of https://github.com/elastic/elasticsearch/pull/28972
Original commit: elastic/x-pack-elasticsearch@8ba2e97b26
In order to more easily integrate xpack once it moves into the
elasticsearch repo, references to the existing x-pack-elasticsearch need
to be reduced. This commit introduces a few helper "methods" available
to any project within xpack (through gradle project extension
properties, as closures). All refeerences to project paths now use these
helper methods, except for those pertaining to bwc, which will be
handled in a followup.
Original commit: elastic/x-pack-elasticsearch@850668744c
This commit removes the usages and definition of deprecated methods that do not accept the XContentType for the source.
Additionally, usages of *Entity classes from the http client library have been changed to always specify the content
type.

This change adds licensing to the maching learning feature, and only allows access to machine learning if a trial or platinum license is installed.
Further, this change also renames `MlPlugin` to `MachineLearning` in line with the other feature plugin names and move the enabled setting to `XPackSettings`
