[CI] Use devel branch commit for OIDN when building Blender (#21926)
Compiler changes broke the OIDN build, but the in-development version
has the failing code removed so just use that.
I chose a specific commit (the one that has the fix) in the `devel`
branch instead of just the `devel` branch overall as we want to lock
down everything except the compiler in these CI jobs. Cherrypicking the
patch didn't apply.
See https://github.com/intel/llvm/issues/21893 for more info.
