flag-o-matic.eclass: Add functions for testing/stipping HIPFLAGS

Browse Source 
HIPFLAFS allows to specify default compilation flags to be used when compiling HIP files.
As environment variable, it is supported in CMake for all projects that specify HIP as language[1][2].
Some flags like -mtls-dialect=* are not supported by HIP compiler; test-flags-HIPCXX can be used to test flags.
