net/mlx5e: Add direct TIRs to devlink rx reporter diagnose

Add "RX resources" tag to the output of rx reporter diagnose callback.
Underneath add tag for direct TIRs, for each TIR expose its tirn and
the corresponding rqtn.

$ sudo devlink health diagnose auxiliary/mlx5_core.eth.0/65535 reporter rx
 ....
