Reland: Add SharedImageRepresentationDawn

The reland adapts for recent changes to the SharedImageFactory and adds
SHARED_IMAGE_USAGE_WEBGPU for use in the test.

This will allow viewing shared images as Dawn textures, for example so
they can be rendered to via WebGPU. This representation is implemented
for IOSurface-backed shared images.

Also adds a test to render an IOSurface backed shared image using Dawn,
and reading it back with Skia.
