Depsgraph: Implement 'ID_RECALC_GEOMETRY_DEFORM'

During a mesh transformation in edit mode (Move, Rotate...), only part of
the batch cache needs to be updated.

This commit allows only update only the drawn batches seen in
`BKE_object_data_eval_batch_cache_deform_tag` if the new
`ID_RECALC_GEOMETRY_DEFORM` flag is used.

This new flag is used in the transforms operation for edit-mesh and
results in 1.6x overall speedup in heavy subdiv cube.
