ES missing coverage in CFE_ES_PoolCreateEx, requires alternate config

Is your feature request related to a problem? Please describe.
Branch/line below uncovered since it would require an alternate configuration:

     284                 :         11 :     Alignment = ALIGN_OF(CFE_ES_PoolAlign_t); /* memory mapped pools should be aligned */
     285         [ -  + ]:         11 :     if (Alignment < CFE_PLATFORM_ES_MEMPOOL_ALIGN_SIZE_MIN)
     286                 :            :     {
     287                 :            :         /*
     288                 :            :          * Note about path coverage testing - depending on the

     291                 :            :          */
     292                 :          0 :         Alignment = CFE_PLATFORM_ES_MEMPOOL_ALIGN_SIZE_MIN;
     293                 :            :     }

code coverage is not possible without changing the configuration.

Currently: Ran on docker with ubuntu 22.10 on windows

1. Alignment = 16
2. CFE_PLATFORM_ES_MEMPOOL_ALIGN_SIZE_MIN = 4

You could add the minimum alignment as a passed-in parameter - then this new function could be called from unit test with a larger value. However because CFE_ES_PoolCreateEx() is part of the API, you'd need to rename the existing function to add the param, then make a compatible CFE_ES_PoolCreateEx() that calls the new function with CFE_PLATFORM_ES_MEMPOOL_ALIGN_SIZE_MIN.
