[PATCH i-g-t] tests/kms_rotation_crc: Add vblank wait for multiplane rotation synchronization

[PATCH i-g-t] tests/kms_rotation_crc: Add vblank wait for multiplane rotation synchronization

[Jeevan B]

Add explicit vblank wait after atomic commit in test_multi_plane_rotation()
to ensure both planes are fully synchronized before CRC capture. This fixes
sporadic CRC mismatches observed on CI.
