feat(drtm): log No-Action Event in Event Log for DRTM measurements

This patch updates `drtm_measurements.c` to ensure that a No-Action
event is recorded in the Event Log as part of the DRTM measurement
process.
This helps maintain compliance with the event logging requirements
specified in DRTM spec v1.1 [1].
