CF Unused type declarations

Checklist (Please check before submitting)

• 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
The static code analysis tools found several instances where a typedef statement defines a type that is not used anywhere in the scope of the typedef.

To Reproduce
Run static analysis tools.

Expected behavior
Code should adhere to Misra2012:2.3: A project should not contain unused type declarations.

Start with the five locations listed in config/default_cf_msgdefs.h, fsw/src/cf_utils.c, fsw/src/cf_cfdp_dispatch.h, and fsw/src/cf_cfdp_types.h, then run the project's static analysis tools. Check each reported typedef against its scope and remove or otherwise address only the unused type declarations. Done means the listed MISRA2012:2.3 findings are resolved without introducing new analysis issues.
