Nikita Sirgienko 2bab4ae370 Cycles: oneAPI: Optimize texture access by using GPU HW sampler

The current usage of software-based texture operations in
the oneAPI implementation puts additional register pressure on
the GPU compiler during register allocation. And it also creates
code that requires maintenance. This commit is intended to address
this situation by utilizing a recently productized SYCL bindless
texture API to enable HW-based texture operations using
Intel GPUs' hardware sampler.

This currently translates to 1-11% rendering speedups (scene-specific)
on my Arc A770 and Arc B580. At the moment, there are small
performance regressions with NanoVDB texture operations on Arc B580
and small performance regressions in shade surface MNEE and Raytrace
kernels on Arc A770, but they look recoverable and will be handled
in the future.

Pipeline Config

The yaml configuration file is used by buildbot build pipeline update-code step.

The file allows to set branches or specific commits for both git submodules and svn artifacts. Can also define various build package versions for use by build workers. Especially useful in experimental and release branches.

NOTE:

The configuration file is NOT used by the ../utils/make_update.py script.
That will implemented in the future.
