dev-vcs/pre-commit: new package

With tests regrettably restricted for now - although their vast majority
(excluding the language/repository ones, which have a lot of
dependencies and do not always handle their absence correctly) passes,
there are 9 which fail due to unspecified problems invoking git.

Closes: https://bugs.gentoo.org/679014
