Subject: chore(ext/webgpu): include GPUCanvasContext in snapshot (#21773)

Part 1 of #21713

Changes:

- Remove `.present()` and add a `presentGPUCanvasContext` (not exposed
yet to users)
- Move lazy load logic to `00_init.js`. This can be used to use webgpu
on-demand from future code (OffScreenCanvas)
