Document DynamicFont limitations and a possible workaround

SCons: Disable -Werror on 'stable' releases

Implement global and per instance shader uniforms.

Add light size to Sky Shaders

Document image size limits

Clarify that angles must be specified as radians in the documentation

Activate Physics Process in SpringArm3D.

Adds two keywords to shader language for uniforms:
-'global'
-'instance'

This allows them to reference values outside the material.

This closes #30014.

This closes #30238.

Use sky properly for ambient and reflections

Stable releases are tagged and need to stay easy to compile in the future.
As new compiler versions introduce new warnings or catch more occurrences,
have -Werror set in tagged releases could be a bother.

We still want it on by default for all Godot developers, so it's now
conditional.

This closes #36356.
