This guards blitting-related functionality of RadioButtons and
CheckButtons behind a `self.canvas.supports_blit` check, so that we
don't get errors when trying to call blitting functionality on canvases
that don't support it.
Note: RadioButtons and CheckButtons do still not fully support canvas
swapping as they carry persitent state that depends on blitting
capability ("animated"). This is currently not updated when canvases are
changed. However, this should at most lead to incorrect rendering
in some edge cases after
canvas swap. It will not error out anymore.
In other words the "# TODO: make dynamic" is partially solved, and
reduced to a smaller problem outlined in the new TODO.

Test failures are the usual flaky suspects :/ |

Closes #30575 (again), in particular this fixes the error during figure close in mne-tests reported in #30575 (comment)
