Brad King cb93f72624 HIP: Simplify detection of HIP runtime CMake package
It only makes sense to use the CMake package from the same ROCm
installation that the compiler uses.  Ask the HIP compiler to report the
location of the ROCm installation.  Verify up front that it contains the
expected CMake package file.
