This node provides the ability to rotate a vector around a `center` point using either `Axis Angle` , `Single Axis` or `Euler` methods.

CUDA devices
Rendering with multiple CUDA devices but denoising with OptiX caused parts of the image to go
missing at the start while the resolution was scaled. This is because the copy operation in
`MultiDevice::map_neighbor_tiles` which slices the copy across all devices would slice based on the
full resolution and not the scaled one and therefore copy incorrect data between devices.
Since this is not the recommended way of using viewport denoising anyway, simply avoid those
incorrect copies for now by disabling denoising while the resolution is scaled. Doing both rendering
and denoising with OptiX is not affected by this, since it avoids those copies altogether anyway.

- Unlock property range.
- Use triangular noise to keep perceptual noise error more uniform.
Remap range to preserve perceptual intensity.
- Center noise distribution around 0 for GPU implementation because of
rounding.
- Do dithering after merging overlays.
Effect of using triangular noise is not really noticeable if you don't use
really low bitdepth. But doing a test in the shader were we artificially
reduce the bitdepth (`col = (col * 16) / 16;`) reveals the real difference.

This modifies the common CUDA implementation for adaptive kernel compilation slightly to support both CUBIN and PTX output (the latter which is then used in the OptiX device). It also fixes adaptive kernel compilation on Windows.

Thanks Patrick Mours for finding it.

* Direction mode X, Y and Z to align with axes rather than diagonal or
spherical as previously. X is the new default, existing files will
use diagonal or spherical for compatibility.
* Phase offset to offset the wave along its direction, for purposes like
animation and distortion.

The user theme is loaded after window creation so we should create the
window with a color that at least matches the default theme.

This adds some extra functions recently added to the float Maths Node.
Not all functions have been ported over in this patch.
Also:
+ Tidy up menu
+ Change node color to match other vector nodes, this helps distinguish vector and float nodes in the tree
+ Move shared OSL functions to new header node_math.h

Sometimes the viewport buffer size is zero for a frame, which caused the denoising task to also try to
launch CUDA kernels with a launch size of zero, which in turn failed with a CUDA error. This patch
prevents launches from occuring in this case, similar to how it is handled in `copy_to_display_buffer`.

Various fixes for smoke / fire flow objects:
- Apply inflow at every subframe (new: also emit during adaptive steps in between frames)
- Fix issue with fire not being emitted on first frame
- Higher value range for smoke flow density variable

MSVC does not have -march=native, so the kernel gets built without AVX2 and
BVH8 support. The code assumed it to be available and crashed

MSVC has a conformance mode (/permissive-) where the C++ standard is more strictly
enforced. This mode is available on MSVC 15.5+ [1]
This patch enables this mode on compilers that support it and cleans up the few violations it threw up in the process.
- Mantaflow was using M_PI without requesting them using the _USE_MATH_DEFINES define to opt in to non default behaviour.
- Collada did not include the right header for std::cerr, this seemingly was fixed for other platforms already but put inside a platform guard.
- Ghost had some scoping issues regarding uninitialized variables and goto behaviour
Second landing of this patch, earlier commit was reverted due to some compiler configurations having slipped though testing

It is breaking compilation on some configurations, revert for now while

This reduces code duplication between the CUDA and OptiX device implementations: The CUDA device
class is now split into declaration and definition (similar to the OpenCL device) and the OptiX device
class implements that and only overrides the functions it actually has to change, while using the CUDA
implementation for everything else.

There were to copies of stdosl.h one from stock OSL
and one in the cycles tree augmented with cycles
specific closures.
moved the cycles ones to stdcycles.h and copied
the stock stdosl.h and accompanying headers from
the OSL shader folder.

The OptiX denoiser can be a great help when rendering in the viewport, since it is really fast
and needs few samples to produce convincing results. This patch therefore adds support for
using any Cycles denoiser in the viewport also (but only the OptiX one is selectable because
the NLM one is too slow to be usable currently). It also adds support for denoising on a
different device than rendering (so one can e.g. render with the CPU but denoise with OptiX).

Fluid guiding functionality was broken in the bake / read cache loop in fluid.c. Committing this to the release branch as otherwise fluid guiding would not have worked as expected (i.e. not at all).
