Remove hip path manipulation

[MarcelKoch]

This PR removes the setting of the HIP_PATH environment variable. It also removes setting the paths for each rocm library individually. Instead, it is expected that user provide the correct CMAKE_PREFIX_PATH during configuration.
Additionally, a check is introduced to warn about rocm's faulty CMake setup. For rocm 5.0-5.6 the default installation (as provided in the rocm/dev images) has some bugs, which prevent even the simplest CMake setup to enable the HIP language.

LGTM. does it also need to wait for the new image?
That will be great if you add the warning to the ReadME or known issue after it is merged
