Embree: avoid potential clashing symbols with external renderer add-ons

Fix: T73830 OSL not finding stdosl.h on linux

This extends FindOpenShadingLanguage.cmake to also look for the location of
stdosl.h and adds the path to the invocation of oslc to deal with the headers
being in different locations a little better.

Fix T71455, T73852, T73860: Transform, Redo doesn't work properly in time editors

The redo panel does not consider the position of the mouse.
So it is not possible to know the direction to redo the operator.

The solution is to add a new `direction` parameter that can be
saved and used for redo.

Fix T73853: Redo does't work properly with NLA "Move" transform mode

The orientation matrix when re-doing some transform operations was negated.
Thanks @lichtwerk for pointing out the problem.

Cycles: Vector Rotate Node using Axis and Angle method

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

Fix artifacts with Cycles viewport denoising when rendering with multiple 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.

Fix T73817: Shape key users not properly mapped when duplicating their obdata.

Once again those crappy weirdos IDs with their crappy weirdos 'loopback'
pointers...

This is a quick hack for now, think id_copy needs to be reworked a bit
to supported re-entrant sub-ID copying (also an issue with nodes I bet).

ColorManagement: Dithering Improvement

- 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.

Fix T68749: BPY: Deprecate height of popup

`invoke_props_dialog` and `invoke_popup` had a width and a height field. The height field was ignored as the height is determined based on the content. This change removes the field from the BPY + WM_api

Fix T73518: Normal Overlay

This change will not render the normals for faces that are hidden.
Before we had instance drawing the hidden faces were registered in the
index buffer. During the overlay refactoring the rendering was migrated
to instance rendering. Instance rendering does not use the index buffer
so the data was ignored.

This patch stored the normal visibility in the .w part of the normal or
for face normals it will set the normal to zero. The shader looks at
this and renders the normals fully transparent when detected.

Cycles: Add support for adaptive kernel compilation to OptiX device

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.

Cleanup: compiler warning

Shading: add direction modes and phase offset to wave texture node

* 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.
