Cleanup: Simplify vector direction comparison

Multiply the two number together. If the sign of the result is positive, then the sign was the same. If the sign of the result is negative, then the signs were different.

PyAPI: Fix memory leak of parameters used for python 'draw_callbacks'

When closing the blender, while the callbacks are removed, the
reference count of the object used as `customdata` is not decremented.

This commit adds two functions that correctly release the
python `draw_callbacks` before releasing all `draw_callbacks`.

Cleanup: Fix comment

Cycles: initial implementation of direct light in new integrator

Only opaque shadows for now.

Cycles: minor optimization for render pass accumulation

Cycles: do more complete shaderdata setup using new integrator state

GPencil: Improve Interpolate AutoFlip algorithm II

Improved the calculation of the distances and changed the variable names to make it more readable.

Still, there are some corner cases that could be not handled properly, but we keep as is to test more real drawings to analyze if the small number of corner cases needs to be fixed or not.

Cleanup: CryptomatteLayer

Missing code flow.

Cleanup: Cryptomatte Use StringRef(Null).

Cleanup: CryptomatteLayer structure.

Current implementation was to restricting for future enhancements where
the CryptomatterLayer could be read from existing metadata.

Cmake/deps: Update OSL to 1.11.10.0

This bumps OSL to 1.11.10.0. OSL Has a new build time
dependency: Clang, and more importantly it expects
clang and llvm to share a library folder, which it
previously for us did not.

This patch changes:

-OSL Update to 1.11.10.0

-refactor the llvm/clang/clang-tools-extra builds into the llvm
build using the llvm-project tarball for building that has all
of the subprojects in it.

-update ispc/openmp builds since clang no longer its own dependency
and they have to depend on the llvm build now.

-Update the windows builder to use the 64 bit host tools since it
ran out of ram linking clang

-Since OSL now needs clang to link successfully a findclang.cmake
has been provided for linux/OSX
