[UR][HIP] Fix include for AMD COMGR

[sommerlukas]

The code object finalization for kernel fusion uses the AMD COMGR. The location of the corresponding header changed between ROCm version 4 and 5.

This PR fixes the include for ROCm version 4.

The rocm_version.h header does not necessarily seem to be present ROCm/HIP installations. Changed the PR to use CMake instead to detect the correct include for the AMD COMGR.
