Describe the contribution

• Fixes UtAssert_StringBufCompare output of strings could be put on top of each other for easier problem identification #1193
  • Comparison strings are now formatted one above the other and aligned to make identifying the discrepancy easier.

An example:

Testing performed
GitHub CI actions and local cFS test suite run all passing successfully.

Expected behavior changes
The change makes it easier to identify the discrepancy between the strings in case of a failed test.

Only slight downside is the increase in length of the test log... (each call to UtAssert_StringBufCompare() now results in 3 lines printed instead of 1).
There are currently ~40 uses of UtAssert_StringBufCompare() in cFE and OSAL.
