Subject: feat(emacs-pkgs/tvl): Add magit shortcuts for reviews & co

Introduces two new shortcuts in the magit popup for pushing:

* R: Push for review
* S: Push to submit

The existing "P" command remains, but has been renamed to
"rubberstamp" and documented with a warning.

To make this work across people's different setups, customisation
options for TVL-specific code are being added.
