The WGSL spec has been updated with 'Default Struct Layouts':
https://github.com/gpuweb/gpuweb/pull/1447
This removes the `[[offset(n)]]` decoration, and replaces it with two optional decorations: `[[size(n)]]` and `[[align(n)]]`, and a sensible set of sizes and alignments for each type.
Most `[[stride(n)]]` decorations have also been removed from arrays.

This is to follow the renames in the upstream WebGPU specification.
Typedef are left in places to make a smooth deprecation period.

CopyTextureForBrowserTests will cover incoming color format conversion
cases. While it is OK for |unorm| formats to compare their pixel values
on the CPU side, we cannot do such comparisons for the |float| formats
because we may meet the precision issues when comparing a value
generated at the CPU side to the one from the GPU side.
Refactor this test suites by using compute shader and do bit-by-bit
comparison from source texture and destination texture.

CopyTextureForBrowser end2end tests had been skipped on Vulkan/Metal
backends due to crbug.com/tint/63.
Because this issue has been fixed, enable CopyTextureForBrowserTests on
Vulkan/Metal backends.
However, D3D12 backend with validation layer still stucks. Raise issue
crbug.com/dawn/592 and keep tests skip.

In previous internal shader, we draw a just fit-in rectangle to do the
copy. But there is arithmetic precision issues in border pixels when
copy from a large texture.
ANGLE handle the same issue by drawing a large triangle. Dawn adopte the
same idea here

This makes a nearly one-to-one mapping between the JS and C APIs, which
benefits projects like Blink and Emscripten.
- JavaScript's `undefined` is equivalent to C `WGPU_STRIDE_UNDEFINED`.
- JavaScript's `0` is equivalent to C `0`.
- To implement the API correctly, Blink must special-case an actual
value coming in from JS that is equal to WGPU_STRIDE_UNDEFINED
(0xFFFF'FFFF), and inject an error.
Keeps but deprecates a reasonable approximation of the old behavior.

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.
