drm/amd/display: Only force modesets when toggling HDR

Browse source

[Why]
We can issue HDR static metadata as part of stream updates for
non-modesets as long as we force a modeset when entering or exiting HDR.

This avoids unnecessary blanking for simple metadata updates.

[How]
When changing scaling and abm for the stream also check if HDR has
changed and send the stream update. This will only happen in non-modeset
cases.
