Initial DLSS implementation (#19864)

# Objective
- Closes #8420

## Solution
- Initial implementation of DLSS upscaling, via
https://github.com/bevyengine/dlss_wgpu.
- Future PRs will work more on transparency, exposure, working with
custom viewports, fixing inevitable resolution override bugs, etc.
- DLSS framegen is not planned, but ray-reconstruction is for solari.
- FSR3/4, XeSS2, and MetalFX temporal upscaling should be easy to add
now if a future contributor wants to. In the future we could have an
auto-temporal AA component that handles DLSS/FSR/XeSS/MetalFX/TAA
fallbacks automatically.

## Testing

- Did you test these changes? If so, how?
  - Run the anti_aliasing example
- Are there any parts that need more testing?
- Different types of scene content and rendering effects to make sure
they work with DLSS/upscaling
  - Reviewing dlss_wgpu code
