patch: do not cache translated messages (API)
Previously the code caches `i18n._` results in module variables. That causes
issues after an encoding change. Instead of invalidating them manually, we
now just recalculate the translated messages every time `filterpatch` gets
called.
This makes test-commit-interactive.t pass regardless of whether chg or
demandimport is used or not.
.. api: `patch.messages` now lives in `patch.getmessages()`.
Extensions adding new messages should now wrap the `patch.getmessages`
method instead of changing `patch.messages` directly.
