drm/i915/display: Handle VSYNC timing in LRR path

LRR already updates crtc_vtotal/crtc_vblank_end seamlessly.
Extend the same handling to crtc_vsync_start/crtc_vsync_end so
VSYNC timing changes are programmed and accepted via the LRR path instead
of forcing a full modeset.

v2: Add comment explaining why TRANS_VSYNC update is safe for DP LRR.
