switch TelecomManager List getters to ParceledListSlice

It was shown that given a large phoneAccountHandles that are
over 1 mb, a TransactionTooLarge exception can be silently thrown
causing an empty list to be returned.

In order to prevent this behavior, all Lists that return a
PhoneAccountHandle or PhoneAccount have been switched to
ParceledListSlice.

bug: 236263294

Test: manual #1 - bug exists without fix,
      manual #2 - bug is fixed with patch,
      4 new CTS tests in
      android.telecom.cts.PhoneAccountRegistrarTest
