[Android] Add Device::GetAHardwareBufferProperties()

This CL adds Device::GetAHardwareBufferProperties(), which will allow
getting the properties of an AHardwareBuffer (notably the YCbCr info)
without having to first create a SharedTextureMemory instance. This is
useful because it turns out that when using external sampling, it will
be necessary to configure the SharedTextureMemory at the time of its
creation so that it correctly creates its VkImage. Having this API on
Device allows clients to determine whether they want to use external
sampling with a given AHB before creating the STM for that AHB.

Note:

* I didn't bother deduping the implementation with that of
  SharedTextureMemory as once this new API is in place Chromium will
  transition to using it entirely and we can remove obtaining the AHB
  properties from SharedTextureMemory

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.
