Cleaning up Unit Test folders

Problem Description

Unit test folders currently contain old binary executable UT files, old R&D checklists, and Google test suite files, gcov files, and old make files.
This ticket will be used to track the subsequent PRs cleaning up UT folders.

How to Reproduce

To list binary files run find . -type f -name runtest_*
To list gcov files run find . -type f -name *.gcov
etc.

Expected Behavior

With the new fprime-util tool there is no need to keep the old executable files or include Google test suite files.

Are there any more outdated ut test files to remove? I think I've found more gcov files in Svc
