Andrea Corallo e866d08d8b contrib: add mdcompact

Hello all,

this patch checks in mdcompact, the tool written in elisp that I used
to mass convert all the multi choice pattern in the aarch64 back-end to
the new compact syntax.

I tested it on Emacs 29 (might run on older versions as well not
sure), also I verified it runs cleanly on a few other back-ends (arm,
loongarch).

The tool can be used to convert a single pattern, an open buffer or
all md files in a directory.

The tool might need further adjustment to run on some specific
back-end, in case very happy to help.

This patch was pre-approved here [1].

Best Regards

  Andrea Corallo
