Update CTS for permission dialogs on Automotive

On Automotive, PermissionController uses a standardized system
dialog. We don't have control over it's layout, so we can't
find views by ids. Switch to finding views by text instead.

This fixes all tests except for the following 2, which
still have issues to be addressed in a followup CL:
android.permission3.cts.PermissionReviewTest#testReviewPermissionWhenServiceIsBound
android.permission3.cts.PermissionTest30#testRequestBothInSequence

Bug: 154947457
Test: make cts, cts-tradefed, run cts -m CtsPermission3TestCases
