Add window support for Deno and WebGPU

[ReddikHaien]

Based on the current progress with the WebGPU(hats off to everyone involved, good job :D), I was wondering if it would be possible to implement window support using raw-window-handle as mentioned in a #7863. I did some tinkering and think a possible solution could be to create a wrapper struct for the window handle. For example:

pub struct WindowResource{
  pub window_handle: &'static dyn raw_window_handle::HasRawWindowHandle
}

impl Resource for WindowResource {
  fn name(&self) -> Cow<str>{
    "WindowResource".into()
  }
}

unsafe impl raw_window_handle::HasRawWindowHandle for WindowResource{
  fn raw_window_handle(&self) -> raw_window_handle::RawWindowHandle{
    self.window_handle.raw_window_handle()
  }
}


impl WindowResource{
  pub fn create_window_resource(handle: &'static dyn raw_window_handle::HasRawWindowHandle) -> Self{
    Self{
      window_handle: handle
    }
  }
}

This could then be passed to webgpu or to a different plugin as a simple rid.

I'm pretty new to Rust, so I hope you'll exuse the terrible implementation above 😅

We are currently working on this, see #10690

Ahh, I see.
Nice👍👍

I'm going to keep the issue open, so we have something to track.

We have abandoned this idea due to various difficulties and complications, and as such am closing this issue. The better approach will be through embedding using a newly added Extension; see gfx-rs/wgpu#3265
