drm/amd/display: Perform plane updates only when needed

[Why]
Our old logic: if pageflip, update freesync and plane address.
Otherwise, update everything.
This over-updated on non-pageflip cases, and it failed to
update if pageflip and non-pageflip changes occurred on
the same commit

[How]
Update flip_addrs on pageflips.
Update scaling_info when it changes.
Update color fields on color changes.
Updates plane_info always because we don't have a good way of
knowing when it needs to be updated.

Unfortunately, this means that every stream commit involves two
calls into DC.  In particular, on pageflips there is a second,
pointless update that changes nothing but costs several
microseconds (about a 50% increase in time taken). The update is
fast, but there are comparisons and some useless programming.

Leave TODOs indicating dissatisfaction.

drm/amd/display: Call into DC once per multiplane flip

[Why]
amdgpu_dm_commit_planes was performing multi-plane
flips incorrectly:

It waited for vblank once per flipped plane

It prepared flip ISR and acquired the corresponding vblank ref
once per plane, although it closed ISR and put the ref once
per crtc

It called into dc once per flipped plane, duplicating some work

[How]
Wait for vblank, get vblank ref, prepare flip ISR, and call into
DC only once, and only if there is a pageflip

Make freesync continue to update planes even if vrr information

drm/amd/display: Only get the connector state for VRR when toggled

[Why]
This fixes a stuttering issue that occurs when moving a hardware cursor
when VRR is enabled.

Previously when VRR is enabled atomic check will grab the connector
state for every atomic update. This has to lock the connector in order
to do so. The locking is bad enough by itself for performance, but
it gets worse with what we do just below that - add all the planes
for the CRTC to the commit.

This prevents the cursor fast path from working - there's more than one
plane now. With state->allow_modeset = true on top of this, it also
adds and removes all the planes from the DC context triggering a full
(very slow) update in DC.

[How]
We need the connector state to get the VRR min/max capbilities, but we
only need them when there's a CRTC mode change or when VRR is toggled.

The condition has been updated accordingly.
