CFE_ES_PerfLogAdd should document config

[irowebbn]

Describe the bug
The docstring for CFS_ES_PerfLogAdd makes no mention that the value of Marker is limited by the config value CFE_MISSION_ES_PERF_MAX_IDS.

In my case, I have never altered this limit and was not aware of its existence, so I was surprised when calls to the CFE_ES_PerfLogEntry were failing. The only way to know that this value is used is to check the implementation file at modules/es/fsw/src/cfe_es_perf.c or the note under from the documentation of sample_perfids.h:

Performance ids are limited to the range of 0 to CFE_MISSION_ES_PERF_MAX_IDS - 1.

This text should also appear in the docstring for CFE_ES_PerfLogAdd

I also find the documentation for CFE_MISSION_ES_PERF_MAX_IDS at modules/es/config/default_cfe_es_interface_cfg.h confusing:

**  \cfeescfg Define Max Number of Performance IDs for messages
**
**  \par Description:
**       Defines the maximum number of perf ids allowed in command/telemetry messages
**
**      This affects the layout of command/telemetry messages but does not affect run
**      time behavior or internal allocation.
**
**  \par Limits
**       All CPUs within the same SB domain (mission) must share the same definition
**       Note this affects the size of messages, so it must not cause any message
**       to exceed the max length.
**
*/

I find this confusing because although the value does affect the size of the CFE_ES_HousekeepingTlm_Payload telemetry message via the filter and trigger mask buffers, the wording does not indicate that this limits the upper value of perfids, not the number of perfids. I could have only a few dozen perfids, but if one had a value greater than or equal to this parameter, it would be rejected.
