Scrub for mismatched function prototype/implementation parameter names

• 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
3 cases of mismatched parameter names between function prototypes and their implementations.
e.g.

PSP/fsw/inc/cfe_psp.h

Line 397 in 6fceb13

int32 CFE_PSP_MemCpy(void *dest, const void *src, uint32 n);

PSP/fsw/shared/src/cfe_psp_memutils.c

Line 69 in 6fceb13

int32 CFE_PSP_MemCpy(void *dst, const void *src, uint32 size)

Expected behavior
Mismatched parameter names can be confusing for maintenance and application programming. Best for them to match for the sake of code clarity.
