Command Code/Enum naming convention inconsistencies

Checklist

• I reviewed the Contributing Guide.
• I performed a cursory search to see if the bug report is relevant, not redundant, nor in conflict with other tickets.

Describe the bug

• Similar to LC issue: Correct naming convention inconsistencies LC#70
  • CS also has a few command code macros that are not consistent with the enumeration identifiers or the command function name (all are cases of 2 words being combined into 1).

Code snips
CS_OneShotCmd()
CS_OneShotCmd_t
CS_ONESHOT_CC (should be CS_ONE_SHOT_CC)

CS_EnableCfeCoreCmd()
CS_ENABLE_CFECORE_CC (should be CS_ENABLE_CFE_CORE_CC)

...and a couple more.

Expected behavior
Identifiers should conform to the cFS/cFE naming convention with regard to consistent use of underscores to make mnemonics clear and readable.
