SWDEV-340761 - Limit the removal of opencl conf file to package removal and provide unique name to icd file

While upgrading packaging in SLES/RHEL, the package to be upgraded is installed first, followed by cleanup of the older one
During upgrade 10-rocm-opencl.conf and icd file is getting removed as part of clean up, since the file name and path is same in different package versions.
Limit the removal of opencl conf file to  uninstall/removal of package and not during upgrade.
Used unique name for icd file
