Resizable UnsafeWindowSurface

[gluethane]

Every time I resize the window, I have to create a new UnsafeWindowSurface.
This causes an extremely high memory leak.
So, adding a resize function to UnsafeWindowSurface would be a good improvement.
Thank you.

I encountered this issue while trying to use deno/webgpu to write some 3D rendering code.

Deno.UnsafeWindowSurface does not support resizing, is there a technical problem with Deno's webgpu that doesn't rely on any window library? If so, is there a correct way to recreate the surface without memory leaks?

This seems to be caused by #24200.

According to Learn Wgpu, developers should reconfigure the surface when its size changed.¹

We need a mechanism to solve this problem. Maybe we could add width and height as optional members of the options argument of GPUCanvasContext.configuration?
