Is your feature request related to a problem? Please describe.
CF_EID_ERR_INIT_CMD_LENGTH is used for reporting invalid MID received, note CF_EID_ERR_CMD_GCMD_LEN and CF_EID_ERR_CMD_GCMD_CC are used for actual ground command processing:

CF/fsw/src/cf_app.c

Lines 321 to 322 in 593d61a

	CFE_EVS_SendEvent(CF_EID_ERR_INIT_CMD_LENGTH, CFE_EVS_EventType_ERROR,
	"CF: invalid command packet id=0x%lx", (unsigned long)CFE_SB_MsgIdToValue(msg_id));

Describe the solution you'd like
Event ID names should make sense, maybe CF_EID_ERR_MID or similar.

Describe alternatives you've considered
None

Additional context

Maybe CF_MID_ERR_EID?
This seems like the most common format in other apps.

Having said that, there is a large variance in formats and order-of-components in names for similar events in other components/apps, so getting to a consistent format at some point in the future would make things easier.

At a glance, there is:
CF_EID_ERR_INIT_CMD_LENGTH
CFE_ES_MID_ERR_EID
CFE_EVS_ERR_MSGID_EID
CFE_SB_BAD_MSGID_EID
CFE_TBL_MID_ERR_EID
CFE_TIME_ID_ERR_EID
CS_MID_ERR_EID
HS_MID_ERR_EID
MM_MID_ERR_EID
SC_MID_ERR_EID
SCH_MD_ERR_EID

Seems very reasonable to go with the most common format - CF_MID_ERR_EID looks good to me...
