backend/drm: GAMMA_LUT_SIZE isn't atomic

Browse source 
GAMMA_LUT_SIZE isn't an atomic property. It can be used with the legacy
interface too. So we can unify both codepaths and remove
wlr_drm_interface.crtc_get_gamma_size.

It's no guaranteed to exist though, so we still need to keep the
fallback.
