Cycles: Resolve recent performance regression in oneAPI implementation for Intel® Arc™ GPUs
Recently, performance with oneAPI have regressed due some recent
changes in Blender itself. This commit's changes is resolving this
and also improve compilation time for oneAPI backend first
execution (or Blender compilation time in case of AoT).
Regression have appeared after 5152c7c152e and not related to the
changes itself, but increase of kernels complexity introduced with
it. Changes in this commit is marking some Blender functions as
noinlined for oneAPI backend, which helps GPU compiler to deal with
this complexity without any negative side-effects on performance.
