Camera: Add Hal version 1 autofocus test cases

Tests should be available for autofocus verification. The new
cases include:
"autoFocus" - Check whether the camera supports autofocus. In case
 auto is supported it will continue and test all available modes that
allow 'autoFocus' calls.
"cancelAutoFocus" - In case auto is supported, the test will trigger
full AF scan and cancel it immediately.
'CameraParameters' functionality is also required and should be included.

BUG: 32022758
Test: compile and run the gtest binary on device
