Describe the contribution

• Fixes Refactor handling of EVS_GetApplicationInfo return to eliminate duplication #1428
  • Refactors (10 cases of) identical handling of error returns from EVS_GetApplicationInfo() into a single helper function.

The function prototype isn't strictly required, given the placement of the function definition, but is probably worth having to improve clarity and ease future maintenance.

Can also be implemented as an if/else if/else block (see below). No strong preference but I've left it as a switch for now.

Testing performed
GitHub CI actions (incl. Build + Run, Unit Tests etc.) all passing successfully.
Tested locally as well and confirmed coverage of all new/amended lines of code via LCOV report.

Expected behavior changes
No impact on behavior. The same events will occur in the same circumstances.

System(s) tested on
Intel(R) Celeron(R) N4100 CPU @ 1.10GHz x86_64
Debian GNU/Linux 11 (bullseye)
Current main branch cFS bundle.
cFE v7.0.0-rc4+dev205

Question:
Does this require new tests, or is the coverage coming through from the calling functions satisfactory?
