[petsc-dev] AMGx integration

[Mark Adams]

Matt, (cc'ing Matt M.).
Thanks, that looks pretty straight forward.

Matt M: I'm not very familiar with the configuration system. It might be
best for you to ask questions directly instead of me hacking this up.

mmg.py (appended) and AMReX.py are
in petsc/config/BuildSystem/config/packages. I'm guessing it will be
easiest to prune and clone AMReX.py (150 LOC)

I have rebased the branch over main and am testing it now.

Thanks,
Mark
