drm/amd/display: Test FreeSync caps update

Browse source

[WHAT]
Add KUnit tests for amdgpu_dm_update_freesync_caps() covering the
DisplayPort invalid-MSA refresh range along with its narrow-range and
valid-MSA-required rejections, an eDP panel advertising replay, the
HDMI AMD VSDB range with and without a parser, a whitelisted DP to HDMI
converter, the forced FreeSync minimum quirk, the MCCS capability
withdrawal and the replay teardown.
