intel-compute-runtime: add conflict with libopencl-mesa

Add RCONFLICTS to prevent libopencl-mesa (mesa's rusticl) and
intel-compute-runtime from being installed together. Both packages
provide OpenCL ICD implementations that conflict at runtime.

The conflict manifests when both ICDs are present in /etc/OpenCL/vendors/,
leading to:
- Multiple OpenCL platforms being detected
- Wrong platform being selected by applications
- Segmentation faults due to LLVM version conflicts between rusticl
  and intel-compute-runtime
- intel-compute-runtime tests failing

Add RPROVIDES for virtual-opencl-icd so intel-compute-runtime can satisfy
OpenCL ICD dependencies from other packages (e.g., intel-oneapi-dpcpp-cpp-runtime).

This ensures only one OpenCL implementation is active, preventing runtime
conflicts for all users.
