Depecrate flags, and try to match them to actions

First, depeprecate the setters for these flags.
Second, of those that it is possible, make them use actions instead.
This isn't possible with isScrollable because it maps to 6 actions,
so just have its setter do nothing instead.
Also fix up a bad unit test.

Bug: 37567816
Test: Ran CTS test suite for accessibiloty, which already test setting
and getting both flags and actions.
Also just ran testback to see if something terrible happened.
