Subject: [PATCH] Use git mirror instead of mercurial for gmp (#392)

cheribuild/pycheribuild/projects/cross/gmp.py is are using MercurialRepository
with a repository of repository = MercurialRepository("https://gmplib.org/repo/gmp").
However, the host for this (quite rightly) blocks certain large IP ranges, namely
all of Azure and Github Actions runners, this causes any build that has GMP
as a dependency to fail.

There is a well maintained mirror hosted on github at https://github.com/gmp-mirror/gmp
which maintains the entire hg repositories commit history and contains some additional branches.
