Implement the webgpu.h swapchains in the frontend and Null backend. The state-tracking of the webgpu.h swapchain is a bit complicated because contrary to implementation-based swapchains, they have more guarantees and a "replacing mechanism". For example instead of hoping the implementation-based swapchain resize automatically, the surface-based swapchain needs to be replaced by a new swapchain and invalidated. This mechanism of invalidation also needs to be triggered when the last reference to the surface is lost because we don't want to risk the application destroying the window from under us. Adds tests for all the cases of invalidation I could think of apart from device loss.

Dawn is an open-source and cross-platform implementation of the work-in-progress WebGPU standard. More precisely it implements webgpu.h that is a one-to-one mapping with the WebGPU IDL. Dawn is meant to be integrated as part of a larger system and is the underlying implementation of WebGPU in Chromium.
Dawn provides several WebGPU building blocks:
