Enable running umfIpcTest tests when free() is not supported

Some memory providers (currently the devdax and the file providers)
do not support the free() operation (free() always returns
the UMF_RESULT_ERROR_NOT_SUPPORTED error).

Add the UMF_TEST_PROVIDER_FREE_NOT_SUPPORTED define
and the get_umf_result_of_free macro() to ipcFixtures.hpp
to enable running umfIpcTest tests when free() is not supported.
