Subject: [PATCH] GHA: separate pytype from other checkers and pips

pytype is discontinued, does not receive further updates, and it
requires older python, offered by Ubuntu 24.04 or older.

Move it to its own GHA job to allow bumping the rest of checkers to.
newer runner images. Also move it out from the shared `requirements.txt`
and install directly from its separate GHA job, to avoid installing it
unnecessarily from others. Since it does not receive update, it's fine
to move out from Dependabot's view.

Ref: https://pypi.org/project/pytype/
Cherry-picked from #22092

Closes #22096
