Implement wrapping IOSurfaces in dawn::Texture.

This allows wrapping IOSurfaces in a dawn::Texture so a Dawn application
can sample from, or render to an IOSurface. It uses Metal's
functionality for wrapping textures in MTLTexture.

Support for single-plane BGRA8, RG8 and R8 IOSurfaces is added as well
as tests for sampling and using BeginRenderPass to clear them.
