[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.
