Fixed code style.

Compositor: Added denoising node

This node is built on Intel's OpenImageDenoise library.
Other denoisers could be integrated, for example Lukas' work.

Compositor: Made OpenImageDenoise optional, added CMake and build_env files to find OIDN

Compositor: Fixed some warnings in the denoising operator

build_environment: Updated OpenImageDenoise to 0.8.1

build_environment: Updated OpenImageDenoise in `make deps` for macOS

Differential Revision: https://developer.blender.org/D4304

GP: Cleanup blend render functions

This is the first step to try to fix the problems with colors.

build_environment: Updated OpenImageDenoise to 0.8.1

Merge branch 'master' into temp-clang-format

partial fix for wrong rotation when converting to keyframes

forgot to initialize ob->quat for passive objects, they are most likely in euler rotation
mode still and the ob->quat seems not automatically in sync

Use 4 spaces for continuations, addresses T53211#611987

Before:

```
if (
psmd->mesh_final->totvert != psmd->totdmvert || psmd->mesh_final->totedge != psmd->totdmedge ||
psmd->mesh_final->totface != psmd->totdmface) {
psys->recalc |= ID_RECALC_PSYS_RESET;

psmd->totdmvert = psmd->mesh_final->totvert;
psmd->totdmedge = psmd->mesh_final->totedge;
psmd->totdmface = psmd->mesh_final->totface;
}
```

After:

```
if (psmd->mesh_final->totvert != psmd->totdmvert ||
psmd->mesh_final->totedge != psmd->totdmedge ||
psmd->mesh_final->totface != psmd->totdmface)
{
psys->recalc |= ID_RECALC_PSYS_RESET;

psmd->totdmvert = psmd->mesh_final->totvert;
psmd->totdmedge = psmd->mesh_final->totedge;
psmd->totdmface = psmd->mesh_final->totface;
}
```

Test not aligning escaped newlines

They're annoying to edit if you ever dont have auto-formatting enabled
and with 100 char width, they may run off the screen.

Fix expanding tabs for 2 space indentation.
