[igt-dev] [PATCH i-g-t v5 18/22] lib/igt_chamelium: Generalize the frame match helper with check type

[Paul Kocialkowski]

In prevision of adding support for another type of frame matching,
rename chamelium_assert_analog_frame_match_or_dump to drop the
analog part and feed it the check type. This way, the bulk of the
helper can apply to other frame matching types.

This requires moving the chamelium_check enum from the test to the
common chamelium header.
