misc: Remove support for checking out as a mercurial repo.

Browse Source 
This will still be technically possible with the right converters, but
this removes the tags, ignore file, and style checking hooks related to
mercurial. We no longer maintain a mercurial mirror of the main git
repository, and this support adds clutter and could diverge from the git
style hooks, etc, over time.
