At first thought this could work. If the ompt header is found offload standalone would set the OMPT support to ON. This would allow us to drop the majority of this top level cmake module. Then that makes the argument for removing it entirely and just put `LIBOMP_HAVE_VERSION_SCRIPT_FLAG` and `pythonize_bool` directly into offload/CMakeLists.txt.
