Remove obsolete comments

[skliper]

Is your feature request related to a problem? Please describe.
End of function comments historically poorly maintained, so not really worth keeping around. Name of a function in comments also frequently gets out of date.

Example of differences (needs full scrub):

to_lab/fsw/src/to_lab_app.c

Line 476 in c20250e

int32 TO_LAB_AddPacket(const TO_LAB_AddPacket_t *data)

to_lab/fsw/src/to_lab_app.c

Line 493 in c20250e

} /* End of TO_AddPkt() */
