Fix deck picker options flickering + error on full sync

https://github.com/ankidroid/Anki-Android/pull/11849#issuecomment-1211775736

Android's onCreateOptionsMenu does not play well with coroutines, as
it expects the menu to have been fully configured by the time the routine
returns. This results in flicker, as the menu gets blanked out, and then
configured a moment later when the coroutine runs. To work around this,
the current state is stored in the deck picker, so that we can redraw the
menu immediately, and then make any potential changes in the background.

Other changes:
- refactored onCreateOptionsMenu to make it simpler
- instead of the sdCardAvailable checks (which I assume is a proxy for
"col is available"), the entire menu is wrapped in a group, and the
visibility of the group is toggled depending on whether the col is available
or not. This also fixes the error on a full sync.
- there are three sets of unit tests (one for search icon, one for sync icon,
one for entire menu) that have been a pain since I originally introduced
this PR, and and I've sunk a number of hours into trying to get them to work
properly at this point. The issue appears to be that when mixing coroutine
calls and invalidateOptionsMenu(), onCreateOptionsMenu() is not getting called
before trying to await the job, leading to a hang or stale data. I tried
advancing robolectric, but it did not help. Maybe someone more experienced
in this area can figure it out, but for now I've changed these routines
to be more of a unit test and less of an integration test: rather than
checking the menu itself, they directly invoke the function that updates
the menu state, and check the state instead. This takes onCreateOptionsMenu()
out of the loop, and avoids the problems (and probably allows these tests
to be re-enabled on Windows as well). The sync tests I've removed, as the
entire menu is hidden/shown now when the col is closed, so they are redundant.
