Support "length" in dawn.json could be a integer

Struct member defined in dawn.json could have a 'length' attribute
defines the length of the member if it is an array.

In previous, the 'length' could only be 'strlen' or other variable
which has 'uint32_t' types. It cannot support constant length.

CopyTextureForBrowserOptions transfers conversion parameters and
conversion matrix with a constant length. This CL adds this ability
to meet such requirements.

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 on Windows 10
    • Metal on macOS and iOS
    • Vulkan on Windows, Linux, ChromeOS, Android and Fuchsia
    • OpenGL as best effort where available
  • A client-server implementation of WebGPU for applications that are in a sandbox without access to native drivers
