* Additional structs added to the hipew loader for device props
* Adds hipRTC functions to the loader for future usage
* Enables CPU+GPU usage for HIP
* Cleanup to the adaptive kernel compilation process
* Fix for kernel compilation failures with HIP with latest master
Ref T92393, D12958
This patch cleans up code for HIP device and makes it more consistent with the CUDA code.
It also fixes the issue with high VRAM usage on AMD cards using HIP allowing better performance and usage on cards like 6600XT.
Added a check in intern/cycles/kernel/bvh/bvh_util.h to prevent compiler error with hipcc

This is required for Cycles to report a meaningful error message when it fails to load a PTX module
created with a newer CUDA toolkit version than the driver supports.
Ref T91879
NOTE: this feature is not ready for user testing, and not yet enabled in daily
builds. It is being merged now for easier collaboration on development.
HIP is a heterogenous compute interface allowing C++ code to be executed on
GPUs similar to CUDA. It is intended to bring back AMD GPU rendering support
on Windows and Linux.
https://github.com/ROCm-Developer-Tools/HIP.
As of the time of writing, it should compile and run on Linux with existing
HIP compilers and driver runtimes. Publicly available compilers and drivers
for Windows will come later.
See task T91571 for more details on the current status and work remaining
to be done.

Several areas within blender can benefit a JSON reader/writer library.
Areas like the asset browser, XR and grease pencil.
After looking at the available options we selected nlohmann's JSON for
modern C++ library. It is actively maintained for over 10 years and
flexible.
This patch only adds the header only implementation of the library so it
can be used by different areas. The asset browser project is planning to
add a small abstraction layer so it will be easier to switch between
several different serialization formats. This is currently in
development in D12544.
In cases the abstraction layer can be an overhead and undesired to be used.
In this case the header file can be directly included.

The XR_MSFT_controller_model OpenXR extension provides a glTF
controller model that can be displayed to users during a VR session.
There are plans to support this in D10948, which will greatly improve
VR immersion when using a compatible OpenXR runtime.
TinyGLTF (https://github.com/syoyo/tinygltf) was agreed upon as a
simple and sufficient solution for loading this glTF controller model,
which will be performed at the GHOST abstraction layer. Although by
default it has two additional dependencies, stb and json, stb can be
excluded by defining TINYGLTF_NO_STB_IMAGE and
TINYGLTF_NO_STB_IMAGE_WRITE whereas json will be added as a separate
extern lib in D12567.

This includes much improved GPU rendering performance, viewport interactivity,
new shadow catcher, revamped sampling settings, subsurface scattering anisotropy,
new GPU volume sampling, improved PMJ sampling pattern, and more.
Some features have also been removed or changed, breaking backwards compatibility.
Including the removal of the OpenCL backend, for which alternatives are under
development.

On the blender side this commit fixes importing video files with audio
and video streams that do not share the same start time and duration.

Refactor and improve waveform drawing.
Drawing now can use line strips to draw waveforms instead of only
triangle strips. This makes us able to properly visualize thin waveforms
as they would not be visible before. We now also draw the RMS value of
the waveform.
The waveform drawing is now also properly aligned to the screen pixels
to avoid flickering when transforming the strip.

The duration and start time for audio strips were not correctly read in
audaspace.
Some video files have a "lead in" section of audio that plays before the
video starts playing back. Before this patch, we would play this lead in
audio at the same time as the video started and thus the audio would not
be in sync anymore.
Now the lead in audio is cut off and the duration should be correctly
calculated with this in mind.
If the audio starts after the video, the audio strip is shifted to
account for this, but it will also lead to cut off audio which might not
be wanted. However we don't have a simple way to solve this at this
point.

(Some minor changes done in the patch)
Contributed by @erik85 in D11400. The idea from this patch was placed in
a more generic context: A new FOR macro has been added that loops
over the neighbors of a cell within a given radius.
Includes update for OpenVDB file IO, i.e. fixes an issue with
compression flag combination that resulted in random segfaults.
Other changes: Cleanup and formatting.
This is an implementation of Enhanced Subpixel Morphological Antialiasing (SMAA)
The algorithm was proposed by:
Jorge Jimenez, Jose I. Echevarria, Tiago Sousa, Diego Gutierrez
This node provides only SMAA 1x mode, so the operation will be done with no spatial
multisampling nor temporal supersampling. See Patch for comparisons.
The existing AA operation seems to be used only for binary images by some other nodes.
Using SMAA for binary images needs no important parameter such as "threshold", so we
perhaps can switch the operation to SMAA, though that changes existing behavior.
Notes:
1. The program code assumes the screen coordinates are DirectX style that the
vertical direction is upside-down, so "top" and "bottom" actually represent bottom
and top, respectively.
Thanks for Habib Gahbiche (zazizizou) to polish and finalize this patch.

All headers in the svn libraries should be
building with /W0 however MSVC 16.8/16.9
has broken this functionality making OpenVDB
emit lots of warnings.
The breakage was reported [1] in august to MS
but they still have not gotten around to
addressing the issue.
This change explicitly suppresses C4251 in the
module that emitted these warnings. As the warning
is useful in other parts of blender a localized
approach is taken rather than a global suppression.

* USD and OpenVDB headers use deprecated TBB headers, suppress all deprecation
warnings there since we have no control over them.
* For our own TBB includes, use the individual headers rather than the tbb.h that
includes everything to avoid warnings, rather than suppressing all.
This is in anticipation of the TBB 2020 upgrade in D10359. Ref D10361.
This updates fixes the following issues (critical for 2.92):
- Issue that prevented dense 'int' grids from being exported (incorrect clip value)
- Issue with particles outside out of domain bounds (position between -1 and 0) not being deleted
Includes improvements for the file IO. Namely, more meta data will be written from now on.
This change is required to prevent IO issues (e.g. T84649) that arised through the use of sparse grids caching (introduced in 2.92).
