drm: Rename struct drm_atomic_state to drm_atomic_commit

The KMS framework uses two slightly different definitions for the state
concept. For a given object (plane, CRTC, encoder, etc., so
drm_$OBJECT_state), the state is the entire state of that object.
However, at the device level, drm_atomic_state refers to a state update
for a limited number of objects.

Thus, drm_atomic_state isn't the entire device state, but only the full
state of some objects in that device. This has been an endless source of
confusion and thus bugs.

We can rename the drm_atomic_state structure to drm_atomic_commit to
make it less confusing.

This patch was created using:

rg -l drm_atomic_state | \
	xargs sed -i 's/drm_atomic_state/drm_atomic_commit/g; s/drm_atomic_commit_helper/drm_atomic_state_helper/g'
mv drivers/gpu/drm/tests/drm_atomic_state_test.c drivers/gpu/drm/tests/drm_atomic_commit_test.c
