nr: add MAC PDU traces for wireshark

The T tracer macpdu2wireshark has been modified to handle the new traces.
The usage is the same as for LTE.

In NR the RACH is logged as an LTE RACH. Maybe we'll change that in the
future. Looking at the source code of wireshark, I could not find any
way to report NR RACH. Maybe they forgot it. Or I did not search correctly...
