Fix various issues in shadow handling of volumes

Properly compute volume shading for all segments before, between and after
surface hits.

Fix incorrect volume stack for shadow rays

Cycles X: tweak a few functions for easier reuse in volume code

Cycles X: restore two more volume stack functions

Cycles X: remove old volume code

Cycles X: refactor path termination in preparation for volume bounces

To support similar logic as transparent and emissive surfaces.

Cycles X: more complete support for volumes

Brings back volume rendering support to what it was before on the GPU. That
means scattering, emissions and heterogeneous volumes with stepping. However
no decoupled or equiangular sampling yet.

Rather than separate homogeneous and heterogeneous code paths, there is only
heterogeneous now. This ensure shader evaluation is only compiled once. Some
optimizations may be possible for the homogeneous case, but that can be looked
at later.

Includes multiple commits, these are split in P2216. We can discuss how
best to review this next week.

Vulkan: Compiler log parsing.

For the vulkan backend we control the compiler and therefore the log
parsing is much simpler then the OpenGL parsers.

This patch formats the log to a better readable/debuggable format so
developers can quickly detect what needs to be done.
