SWDEV-345870 - Correct HIP path for new directory layout

With file reorganization changes HIP is installed in /opt/rocm-ver
Using HIP path as /opt/rocm-ver/hip will generate warnings
Use real path with symlinks resolved, so that HIP path always points to the installed path
Removed redundant code for finding hsa header files. find_dependency to hsa-runtime should handle hsa dependency
