Embed OpenCL tracing files in the repo

[mabraham]

Formerly these were obtained from a fixed commit from https://github.com/intel/compute-runtime.git. This has no advantage compared with directly embedding the files. It makes the tools hard to build on a cluster without internet access.

The git hash from which the embedded copies are taken was ca7d47598a63959d42750c62a2981e08ffa392a1 and has been recorded in those files. That was the only modification to the files.

The copies were embedded in a subdirectory matching those from the repo from which they were taken, so no modifications to these files are needed in order to use them. All tools in this repo already add the utils subdirectory as a directory in which the compiler should search.

Also minor related changes and simplifications.
