Values for TriggerMode provided to CFE_ES_StartPerfCmd are not documented

[irowebbn]

Describe the bug

Here is the documentation for the CFE_ES_StartPerfCmd_Payload struct:

10.39.2.1 TriggerMode uint32 CFE_ES_StartPerfCmd_Payload::TriggerMode
Desired trigger position (Start, Center, End)
Definition at line 279 of file default_cfe_es_msgstruct.h

There is no indication what values correspond with Start, Center, and End.

Some searching reveals that the implementation in modules/es/fsw/src/cfe_es_perf.c compares for values CFE_ES_PERF_TRIGGER_{START,CENTER,END}. The public header /modules/es/fsw/src/cfe_es_perf.h has the enum values for this, but there is no docstring and therefore does not appear in the user guide. The actual default numeric values would be good to indicate somewhere because the commanding interface may not have access to the CFE_ES_PERF_TRIGGER* macros, ie, when using cmdUtil from the command line.
