drm/amd/display: Test dp_handle_test_pattern_request patterns

Browse source

[WHAT]
Add KUnit tests for dm_helpers_dp_handle_test_pattern_request() covering
the link test pattern mapping, the colour space mapping, the bit depth
change that retimes the stream, and the case where no connector is
available to store the original timing.

[HOW]
Fake link service and clock manager callbacks record the requested
pattern instead of programming the PHY or the clocks.
