FindOpenMP: Add support for HIP clang device pass
The HIP clang makes 2 passes when compiling HIP programs: the DEVICE
pass and the HOST pass. For openmp, the `-fopenmp` option is only
passed to the HOST compilation pass. Therefore, the small test that
CMake uses for OpenMP detection fails to compile, and CMake reports
failure to detect OpenMP support in the compiler. The suggested
solution is to add check for `__HIP_DEVICE_COMPILE__` macro defined by
HIP clang for the DEVICE pass to the OpenMP detection test.
