[YUV AHB] Add a ColorSpaceDawn structure for input YUV color space.

This will be useful to marshall data between Kotlin and Dawn for the
color space conversion of imported YUV AHBs.

The source color space is very flexible because it can represent any
variety of data produced. In particular it contains YCbCr range and
matrices, and decouples the transfer function from the primaries.

Destination color spaces are less flexible and must use one of the
PredefineColorSpaces (to which linear variants are added).

Also update the Kotlin build file and tests.

Finally allow enum value conflicts with "is_proxy" as the transfer
function for sRGB and Rec709 are the same (by design) but we want
developers to be able to use either of the names.

Dawn, a WebGPU implementation

Dawn is an open-source and cross-platform implementation of the 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.
