Denoising support for Metal in bevy_solari #26307

What problem does this solve or what need does it fill?

Currently the bevy_solari renders a noisy ray-traced image on Metal.

I would like to add support to bevy_solari for MetalFX Ray Reconstruction, which will help to use hardware accelerated denoising for ray traced scenes in real-time.

What solution would you like?

• Review and ship the pull request Solari MetalFX Denoising support #26306
• Adopt the accompanying crate into the bevyengine Github organization.

Link to the crate:
https://github.com/mate-h/metalfx_wgpu

What alternative(s) have you considered?

Alternatives have not been considered, instead this solution pattern is taken from dlss_wgpu. We aligned on the solution with bevy_solari maintainer @JMS55 .

Additional context

Solari on Metal support landed on #25123 and shipped with bevy 0.20. We've been getting requests by bevy users on discord for MetalFX support, both supplying their own attempt at the implementation with coding agents. I have consolidated our combined effort into the pull request and crate.
