Fix flipY logic in CopyTextureForBrowser()

CopyTextureForBrowser() handles flipY by flipping source texture then
applying copy op. But this is not correct. Instead
it should find the copy rect and apply flipY op in copy rect only,
which is the same as WebGPU GPUImageCopyExternalImage.flipY definition
(https://www.w3.org/TR/webgpu/#dom-gpuimagecopyexternalimage-flipy).

This CL fixed the issue and updated related end2end tests.

Dawn, a WebGPU implementation

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:

  • WebGPU C/C++ headers that applications and other building blocks use.
    • The webgpu.h version that Dawn implements.
    • A C++ wrapper for the webgpu.h.
  • A “native” implementation of WebGPU using platforms' GPU APIs: D3D12, Metal, Vulkan and OpenGL. See per API support for more details.
  • A client-server implementation of WebGPU for applications that are in a sandbox without access to native drivers
  • Tint is a compiler for the WebGPU Shader Language (WGSL) that can be used in standalone to convert shaders from and to WGSL.
