Nikita Sirgienko 88d90a8251 Cycles: oneAPI: Improve performance of scenes not using volume
buildbot/vexp-code-patch-coordinator Build done. Details 
The NODE_VOLUME feature adds a lot of code to shade_surface,
including the entire NanoVDB library, causing GPU compilers to
spend additional registers while the feature is not used often.
This leads to suboptimal execution and the use of a specialized
version gives a noticeable speed-up for oneAPI devices.

Nikita Sirgienko b515f4a388 Cycles: Fix kernel features reporting of PointDensityTextureNode 
The shader node PointDensityTextureNode can include SVM node which
requires the NODE_VOLUME feature under certain conditions. This
requirement wasn't reported to the shader node manager so it would
lead to incorrect rendering with devices adapting kernels
compilation based on used features.
