Enhance test environment for input

Use real Car Service in the input fragment in KitchenSink app.
This is done through injecting events through back-door property
of emulated VHAL, in this case events tergeting cluster will be
delivered to OEM provided service

Use InputMethodManager to inject KeyEvent into sample cluster main activity

Bug: 74616964
Test: manual kitchen sink + cluster display, verify that taping on
Left/Right steering wheel buttons in kitchen sink switches facets in the
cluster
