validators: T4795: migrate mac-address python validator to validate-value

Instead of spawning the Python interpreter for every mac-address to
validate, rather use the base validate-value OCaml implementation which
is much faster.

This removes redundant code and also makes the CLI more responsive.

Validator is moved out to a dedicated file instead of using XML inlined <regex>
for the reason of re-usability. So if that regex needs to be touched again - it
can all happen in one single file.
