Describe the contribution
Fixes #497

Testing performed
Ran the native_std commands which includes prep, install, runtest, and lcov. Compared these lcov results against the unchanged cFS bundle and found no changes. Ran the old build commands with unit tests enabled to ensure that the internal static code analysis tool no longer flags these functions. Also ran the bundle with -Wunused flags which only flagged unrelated macros.

Expected behavior changes
Removes four dead functions

1. UT_Set_Exception_StorageReadWrite
2. UT_Get_Exception_Size
3. UT_Get_Exception_TotalStorageSize
4. UT_Set_Exception_StoragePtr

System(s) tested on
RedHat, cFS dev
