feat(unittests): add a unit test framework.
This patch adds all the infrastructure needed to run unit tests for
RMM, including a new variant for platform host, called `host_test`.
To build and run the tests:
cmake -DRMM_CONFIG=host_defcfg -DHOST_VARIANT=host_test \
-DCMAKE_BUILD_TYPE=Debug -S ${RMM_SOURCE_DIR} -B ${RMM_BUILD_DIR}
cmake --build ${RMM_BUILD_DIR} -- run-unittests
