d42f4b3ca5 Reland "CopyTextureForBrowser: Support color format conversion"
This is a reland of f84daa070f05eb80672a9a23e23aed205fe72a5e

Eliminate static initializer(disallowed in Chromium) by replacing
shader string living in anonymous namespace from type "std::string"
to char array.

afcef3ee90 Query API: Test the accuracy of timestamp compute shader
Because the uint64 is not supported on all GPU drivers, we use uint32
and float to simulate the multiplication of uint64, but there is
accuracy loss between the results and the expected results computed by
uint64. This test checks that the accuracy loss is less than 0.2%.

cf820d79ef Rename STRIDE_UNDEFINED to COPY_STRIDE_UNDEFINED
Per https://github.com/webgpu-native/webgpu-headers/pull/71

Keeps but deprecates WGPU_STRIDE_UNDEFINED/wgpu::kStrideUndefined.

db8766bb23 Support internal pipelines for Dawn
Like copyTextureCHROMIUM in Chromium, CopyImageBitmapToTexture can use
internal pipeline to do the GPU uploading. But Dawn doesn't support
internal pipeline now.

This patch adds the first internal pipeline for Dawn and add the API
CopyTextureForBrowser to use internal pipeline to do gpu uploading.

The patch integrates very simple wgsl vertex/fragment shaders to do
simple direct blit to verify the whole system works.
