Add restricted settings UI in Settings accessibility screeen

Browse Source 
If OP_ACCESS_RESTRICTED_SETTINGS is rejected, it means accessibility page
for that app is gray out and app info won't show "unlock restricted settings menu"

If OP_ACCESS_RESTRICTED_SETTINGS is ignored, it means accessibility page
for that app is gray out, but app info shows "unlock restricted settings menu"

If OP_ACCESS_RESTRICTED_SETTINGS is allowed(default), it means users can
access accessibility page for that app.

OP_ACCESS_RESTRICTED_SETTINGS will be changed to ignored if user visited
the restricted settings dialog.

OP_ACCESS_RESTRICTED_SETTINGS will be changed to allowed if user passes
the confirmation screen.

Bug: 202130031
Test: Tested the UI and it works correctly
