USD import: remove Convert to Z Up option.

Removing the z-up conversion option, per suggestion
from reviewers.

Tests: Added threshold to physics ocean mesh test

The physics_ocean test is currently failing on macOS arm.
This is one attempt to fix this issue.

Collada import: use black for Base Color when missing <diffuse>

Treat a missing <diffuse> the same as a black diffuse color.

The easiest way to see this bug is with a Collada shader like

```
<constant>
<emission>
<color sid="emission">1 0 0 1</color>
</emission>
</constant>
```

The Collada spec says this should be just

```
color = <emission>
```

ie. red everywhere. The importer slots the red into the Principled Emission socket, but since it leaves the Base Color as the default off-white, this is added to red, and the material looks white-pink in the light and red only in the shadows.

Putting black in the Base Color makes it look red everywhere.

D10939 will also eliminate the much-less-noticeable specular term for this case.

Rename public getInputOperation to get_input_operation

Merge branch 'blender-v2.93-release'

refactor: minor changes to previous commit
- rename boolean is_zero by more descriptive has_specularity
- add some clarifying comments (and TODO)

Collada import: respect zero-specularity

Collada shaders with black <specular> should import with Specular=0.
(A missing <specular> is the same as black.)

The general specular conversion is hard, but this case is common and easy.
Fixes the specular for all <constant>/<lambert> shaders, and <blinn>/<phong>
shaders with black/omitted <specular>. Before this they all looked too "shiny".

Fix T85892: disable progressive refine when using adaptive sampling

This is giving too bright pixel values, as the sample scaling and random number
sample are wrong. The proper fix for this is complicated. It will be solved in
Cycles X, for now we disable this combination.
