Higher quality bicubic lightmap sampling (#16740) 
# Objective
- Closes https://github.com/bevyengine/bevy/issues/14322.

## Solution
- Implement fast 4-sample bicubic filtering based on this shader toy
https://www.shadertoy.com/view/4df3Dn, with a small speedup from a ghost
of tushima presentation.

## Testing

- Did you test these changes? If so, how?
  - Ran on lightmapped example. Practically no difference in that scene.
- Are there any parts that need more testing?
  - Lightmapping a better scene.

## Changelog
- Lightmaps now have a higher quality bicubic sampling method (off by
default).
