[Mac] Simplify Metal descriptor creation for SharedTextureMemory

InitializeFromSharedTextureMemoryIOSurface() currently calls
CreateMetalTextureDescriptor() when creating single-planar textures. The
latter function is very general-purpose, whereas textures created from
SharedTextureMemory have several fixed configuration parameters by
SharedTextureMemory semantics and validation. This CL duplicates and
simplifies the code from CreateMetalTextureDescriptor() inline into
InitializeFromSharedTextureMemoryIOSurface(). This will facilitate
relaxing Metal texture usages for this use case in a followup CL as well
as moving this code into SharedTextureMemoryMTL.

This CL also makes a small related simplification for the multiplanar
case: the sample count can be hardcoded to 1 due to SharedTextureMemory
semantics rather than passing GetSampleCount().

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.
