- BKE_mask_update_scene was only used with do_newframe=FALSE, removed this argument. - Made it so BKE_mask_update_scene is able to handle LIB_ID_RECALC_DATA case. Namely, if mask ID is tagged for data update it means shapekeys will be re-evaluated (as if do_newframe=true). If mask id only tagged for LIB_ID_RECALC, then no shapekey evaluation happens (same as it used to behave before). This means, doing DAG_id_tag_update(&mask->id, OB_RECALC_DATA) will lead to shapekeys re-evaluation which is really needed in such operators as clearing shapekeys (and cleaning shapekeys which is in tomato branch yet). This is a bit silly to use OB_RECALC_DATA sine mask is not an OB, but could not see better way to do it now. This fixes missing mask re-evaluation after clearing shapekey, would expect no other functional changes.
