[Mac] Pass all usages when creating MTLTextures for SharedTextureMemory

This CL makes the following change: When creating MTLTextures from
IOSurfaces vended by SharedTextureMemory, we now pass all Metal texture
usages. This will facilitate an upcoming change to have
SharedTextureMemory cache MTLTextures. See discussion in [1] and its
following comments for both (a) why this is necessary and (b) why it is
not harmful to performance.

Note: As this CL is a functional change, I tested it manually in Chrome
with the WebGPU github examples as well as with Graphite enabled (both
on the WebGPU github examples and just general rendering for Graphite).
Everything renders unproblematically and without any error messages
being generated.

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.
