Requires #508

Note on cargo-gpu: Branch Rust-GPU/cargo-gpu#142 is required to use this PR

Upgrade the toolchain to nightly-2025-10-24, which is the branch day of rustc 1.92.0. This toolchain upgrade is important for people not using cargo-gpu and wanting to use wgpu v28.0.0, which has an MSRV of 1.92.0.

This branch based on #508 by @fee1-dead, but rebased on main (to resolve conflicts with this branch). Extra thank you for figuring out the MaybeUninit::uninit change that broke rust-gpu, which enabled this upgrade. Then I extracted the "first" toolchain upgrade to nightly-2025-11-02 from PR #460 by @dvdplm, lowered the toolchain back down to nightly-2025-10-24, and cleaned it up a bit.

Best reviewed commit by commit.

The next toolchain upgrades based on this branch are:

Tested on: nanite-at-home, ReSTIR, abundance

close #405

@Firestar99 would appreciate a rebase to main again here :)
