Add READ_PHONE_STATE back to phone group

READ_PHONE_STATE was previously removed from the phone group when it
was downgraded to an install permission. Now that READ_PHONE_STATE is
being reverted back to a runtime permission it needs to be added back
to the phone group.

Bug: 154368168
Test: Manually verified app requesting READ_PHONE_STATE is prompted
      with phone group permission prompt.
