Update wgpu to 26 and wasm-bindgen to 0.2.100

[torokati44]

• I have followed the instructions in the PR template

There are new duplicate crates in the dep tree (core-*), but ndk-sys is deduplicated in exchange.

Preview available at https://egui-pr-preview.github.io/pr/7340-wgpu-26
Note that it might take a couple seconds for the update to show up after the preview_build workflow has completed.

Is the wgpu version upgrade blocked by something? I'd be interested in pushing this as I need it for an own project. Can I help somehow?

[Kumpelinus]

Currently the issue seems to be that wgpu is now no_std and the macro from the puffin crate still pulls in std components in the expanded macro (like std::sync::OnceLock) which doesn't work with no_std ofc. I will probably take a look at fixing this later today. (The demo app does compile without the profiling/profile-with-puffin feature so that seems to be the only blocker besides the macOS Issues)

[Kumpelinus]

@torokati44 should I open a different PR or should I edit your existing one (If you give me access to the branch)?

[Kumpelinus]

I’m not sure which crate should host the fix. The underlying issue lies in puffin, which is currently unmaintained, so the patch could land in one of four places:

• the egui-examples crate the error is happening in (other egui users will likely hit the same problem),
• the egui crate itself
• wgpu, or
• the profiling crate.

@Kumpelinus I think it's easier if you open your own, I won't mind. I don't think this permission can be easily granted to you.

[Kumpelinus]

Ok, will do 👍

[nicoburns]

I think bumping arboard will fix the duplicated core-* dependencies

[torokati44]

Are you sure? I wasn't able to do it that way...
