TexturePaint: Missing Texture Depth Test

Depth testing was off as it used the precomputed ModelView matrix. As
draw engines currently use a different approach the depth was sometimes
a bit off making the color disappear.

This change will use a different vertex shader that will write the
correct depth. I expected the same change to be needed in the bone
selection overlay but was not able to reproduce it.

Workbench: World Space Cavity

When using the world space cavity shader together with viewport or image
rendering only a single pattern was used. This was that the iteration of
the cavity shader was updated when the cache is initialized.

Now the cavity iteration is updated together when the TAA samples are
updated.

Sound: Port to a copy-on-write concept

This change makes it so sound handles are created for evaluated scene,
sequencer and speakers. This allows to have properly evaluated animation
on them.

For the viewport playback sound uses regular dependency graph.

For the final render sound uses dependency graph created for render pipeline,
which now also contains sequencer and sound datablocks.

All the direct sound update calls are replaced with corresponding dependency
graph recalc tag.

Depsgraph: Store recalc tag in ID->recalc

Allows to have more granularity in checks compared to a node-factory
based tagging in a generic tag/flush code.

Cleanup: Make comment around DEG evaluation functions more clear

Python GPU Shader: Fix crash when uniform is not found.

Fix empty name shown for operators opening menus without a title

For some cases like the edit mode context menu we don't currently have a fixed
title since it's dynamic. This should be improved, but we should at least still
show Call Menu if there is no menu title.

update Collada Importer: reworked export and import of Materials

- added import of transparency and emission into principled BSDF Shader
- added support for importing all default collada material parameters

* diffuse
* emission
* index_of_refraction
* shininess (mapped to BSDF Roughness)
* reflectivity (mapped to BSDF Metallic)
* transparency + transparent mapped to BSDF Alpha)
* ambient (creates unconnected texture node)
* specular (creates unconnected texture node)
* reflective(creates unconnected texture node)

- added support for exporting collada material parameters:

* diffuse
* emission
* index_of_refraction
* shininess (mapped to BSDF Roughness)
* reflectivity (mapped to BSDF Metallic)
* transparency + transparent mapped to BSDF Alpha)

- prepared support for exporting the following parameters
but currently commented out:

* ambient (creates unconnected texture node)
* specular (creates unconnected texture node)
* reflective(creates unconnected texture node)

Problem: For now we only allow export of principled BSDF based
materials. I am not sure from where to get ambient, specular
and reflective as those values are not included in the
principled BSDF Shader (wip).

Fix T65298 Eevee: Principled BSDF doesn't use specular with metals

This does add some more register pressure as it passes a new vec3 down
the shading function. But for now we care more about accuracy than
efficiency.
