Convert more Perl build scripts to Python

Continue the slow trend of removing Perl from our build process, and
move to a more sustainable (at least by number of developers who know
the language) language: Python.

Use generative AI to convert 3 Perl scripts to Python: mpif-values.pl,
gen-mpi-mangling.pl, and gen-mpi-sizeof.pl.  Validate the results by
code review+inspection and diff'ing the results of the
Python-generated files with the original Perl-generated files.
