[llvm] [SYCL][LLVM] Adding property set I/O library for SYCL (PR #110771)

[Tom Honermann via llvm-commits]

https://github.com/tahonermann requested changes to this pull request.

I don't see motivation for adding an additional base64 implementation to LLVM. If improvements to the existing base64 implementation are desired or warranted, please evolve the existing implementation rather than adding an additional one.
