Add option to GrContext::flush for GrPrepareForExternalIORequests.
This will allow clients to specify a set of SkImages and SkSurfaces that they
want transitioned to a state which they can use for their own external IO.
Specifically for Vulkan this will move the surface and images back to the queues
in which they were originally wrapped or created with.
