Merge remote-tracking branch 'origin/gnb-mac-stats-cleanup' into integration_2025_w27 (!3497)

Browse Source 
Update/refine gNB MAC stats, update L1

Only applicable with -q option.

Print a number of statistics, e.g., rx_ulsch_sdu to track UL MAC stats
timing. Remove unused time_meas_t definitions, and fix the name for the
total gNB scheduler time.

Print the RU stats in nrL1_stats.log, as some are already there, and do
not "pollute" the periodic logs when -q is enabled.

I used this to see why there are sometimes late slots with Aerial. I
used the above stats to get a general overview. This additional patch
shows that at least in RFsim, the RLC indication in rx ulsch sdu can
take up to 20us on my machine. Given that we can have multiple PDUs in
UL (10?), this can amount to a sizeable amount of time. While this is
for another MR, I thought the cleanup would be nice to have.
