freedreno: re-order support for hw queries

Push query state down to batch, and use the resource tracking to figure
out which batch(es) need to be flushed to get the query result.

This means we actually need to allocate the prsc up front, before we
know the size.  So we have to add a special way to allocate an un-
backed resource, and then later allocate the backing storage.
