hw/i3c: keep _bytes aliases for renamed queue-capacity properties

Browse Source 
The command-response/tx-rx/ibi queue-capacity properties were renamed
from "-bytes" to "-words".  The "-bytes" names are user-visible and
shipped in v11.0.0 (reachable via e.g.
-global driver=dw.i3c,property=tx-rx-queue-capacity-bytes,...), so
register them as aliases of the new names to keep existing command
lines working.

object_property_add_alias() forwards both reads and writes to the
target property, so the old names behave exactly as before; introspection
and qom-get/qom-set continue to work under either name.
