[m134] metal: Specify storage binding usage for IOSurface textures explicitly

Add a allowStorageBinding flag on SharedTextureMemoryIOSurfaceDescriptor
which specifies whether TextureUsage::StorageBinding is allowed and if
MTLTextureUsageShaderWrite is set on the IOSurface wrapping MTLTexture.
The flag defaults to true to match current behavior, but we will change
it to false once Chromium migrates to using the flag. Chromium will set
the flag based on whether SHARED_IMAGE_USAGE_WEBGPU_STORAGE_TEXTURE
usage is set on the IOSurfaceImageBacking.

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.
