xfs: enable the zoned RT device feature

Source kernel commit: be458049ffe32b5885c5c35b12997fd40c2986c4

Enable the zoned RT device directory feature.  With this feature, RT
groups are written sequentially and always emptied before rewriting
the blocks.  This perfectly maps to zoned devices, but can also be
used on conventional block devices.
