BREAKING(webgpu/unstable): move width and height options to UnsafeWindowSurface constructor

[littledivy]

Fixes #23508

width and height are required to configure the wgpu surface because Deno is headless and depends on user to create a window. The options were non-standard extension of GPUCanvasConfiguration#configure.

This PR adds a required options parameter with the width and height options to Deno.UnsafeWindowSurface constructor.

// Old, non-standard extension of GPUCanvasConfiguration
const surface = new Deno.UnsafeWindowSurface("x11", displayHandle, windowHandle);

const context  = surface.getContext();
context.configure({ width: 600, height: 800, /* ... */ });

// New
const surface = new Deno.UnsafeWindowSurface({
  system: "x11",
  windowHandle,
  displayHandle,
  width: 600,
  height: 800,
});

const context  = surface.getContext();
context.configure({ /* ... */ });

Seems ok, but maybe we should just make this a single option bag for everything now?

const surface = new Deno.UnsafeWindowSurface({
  system: "x11",
  displayHandle,
  surfaceHandle,
  width: 600,
  height: 800,
});

const context  = surface.getContext();
