Display a checkerboard pattern on the fallback 3D material #71774

Marked as draft, as this currently affects the Display Lighting debug draw mode. This debug draw mode should be modified to use a different, untextured fallback material.

This has two benefits over a plain untextured surface:

It looks better, and gives a better first impression of the engine's visuals.
- As a bonus, the checkerboard pattern helps make color banding and shadow dithering patterns less noticeable (closer to how it'd be in most finished projects).
It has better usability, as the checkerboard gives you a sense of scale.

This shader is based on @CptPotato's procedural checker shader.

This closes godotengine/godot-proposals#6138.
