Kostia Balytskyi e75b9fc1b1 fb-hgext: move most of hgext3rd and related tests to core
Summary:
This commit moves most of the stuff in hgext3rd and related tests to
hg-crew/hgext and hg-crew/test respectively.

The things that are not moved are the ones which require some more complex
imports.


Depends on D6675309

Test Plan: - tests are failing at this commit, fixes are in the following commits

Reviewers: #sourcecontrol
