Update hip support for Cached CMake Packages (#49635)

Browse Source 
* Clearly split old and new hip settings requirements
* Apply generic rocm handling to every project
* make default logic for hip support more robust
* GPU_TARGET is only necessary under certain project specific conditions, it should not be necessary in general
* Update logic to find amdclang++
