REST API: Expose revision count and last revision ID on Post response

So that REST API clients can show appropriate UI for a post's revisions, it needs to know how many revisions the post has, and what the latest revision ID is.

Merge of [43439] and [43441] to the 4.9 branch.

Props kadamwhite, danielbachhuber, birgire, TimothyBlynJacobs, pento.
Fixes #44321.
