CTS tests for rotary IME configuration

On cars with rotary, perform the following tests:
1. If the OEM specified a rotary IME, confirm that it's an existing IME.
2. Verify that the default touch IME is specified and that it's an
   existing IME.

This CL works around b/184973707 by skipping over the header text. This
workaround should be removed when the bug is fixed.
