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.
