Remove old code that added extra updates for shaders that have a dependency on
objects. The dependency graph can now tell Cycles when a material is affected by
an object transform.
The issue was the usage of the global `__main__` Python module.
When running scripts in the text editor, Blender would overwrite
the `__main__` module.

With the Oculus runtime, the VR session would freeze when taking off the HMD
and putting it back on. This was caused by the deletion of graphics resources
too early in the OpenXR state machine, at least for Oculus.
The resources will now only be freed once the session is actually destroyed.
Also fixes an issue where it wasn't possible to stop the session via the UI
when the HMD was taken off.

Recent changes assumed OpenCL 2.0 platform. This adds a check to see if
we are compiling on an OpenCL 2.0 platform.
Patch was tested on:
* AMD Radeon Pro WX 7100 with amdgpu-pro-19.50-1011208-ubuntu-18.04 drivers
* AMD Vega 64 with amdgpu-pro-20.10-1048554-ubuntu-18.04 drivers

Looping over all primitives for every object is really slow, so this patch avoids that by moving
the necessary assignments inline with the primitive merging done for every geometry.
This patch will add some compiler hints to break unrolling in the
nestled for loops of the voronoi node.

Caused by rB00466e756e33.
While that commit sounds logical, Cycles uses is_updated_transform() to
detect updates.
Now introduce is_updated_shading() and use that on top.

Was happening when only partial subset of callbacks was specified.
The reason was that there was a callback to specify edges sharpness
but no callback to specify vertex sharpness, so the special case for
non-manifold edges was not run.

This reverts commit 1a3928f33c and 1a3928f3. This is not working stable
with some Wintab implementations, so reverting for now. This leaves only
the Windows Ink changes for 2.83.
CMake: `WITH_CYCLES_DEVICE_OPTIX` did not respect `WITH_CYCLES_CUDA_BINARIES` causing the optix kernel to be always build at build time.
Code: `device_optix.cpp` did not count on the optix kernel not existing in the default location.
For this to work, one should have before starting blender
1) working nvcc environment
2) Optix SDK installed and the OPTIX_ROOT_DIR environment variable pointing to it which is not set by default

Currently in fractal_noise functions, each subsequent octave doubles the
frequency and reduces the amplitude by half. This patch introduces Roughness
input to Noise and Wave nodes. This multiplier determines how quickly the
amplitudes of the subsequent octaves decrease.
Value of 0.5 will be the default, generating identical noise we had before.
Values above 0.5 will increase influence of each octave resulting in more
"rough" noise, most interesting pattern changes happen there. Values below
0.5 will result in more "smooth" noise.

Rather than using the last state of the tablet, we now query the history of
pointer events so strokes can follow the pen even if Blender does not handle
events at the same rate.
