drm/amd/display: Add frame skip feature support flag
[WHY]
The set_replay_frame_skip_number() function should not execute when
the link does not support the Frame Skipping feature.
[HOW]
Add a new field `frame_skip_supported` to struct replay_config to
indicate whether the link supports frame skipping. Check this flag
at the beginning of set_replay_frame_skip_number() and return early
if the feature is not supported.
