SWDEV-411086 - Provide path ROCM_PATH/llvm via the HINT argument instead of PATH in calls to find_package

PATHS have lower priority than system paths so if there is a clang installation in /usr/local find_package(Clang)
will pick that instead. To fix this provide the llvm path via the HINTS argument instead.
