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.
