UT Assert library for CFE functional tests

[jphickey]

Is your feature request related to a problem? Please describe.
There is a need to do functional testing of CFE itself along with apps and libraries. These would benefit from using the same assert macros and test framework as the coverage tests use.

Describe the solution you'd like
This can be done by compiling the same UT assert framework as loadable CFE app.
