unit test framework

[Sam Price]

was reading through
https://docs.rtems.org/branches/master/eng/test-framework.html#test-framework-requirements-for-rtems

t.h
I think needs changed to test.h or rtems/test.h

Was trying to stand up a test framework for my board.
Wanted command line arg support though so switched to trying doctest/gtest.
The code in rtems didnt seem to use cli / shell support to launch the
test suite.
