I would expect to find the SharedMemory creation type stuff over here instead of
inside Create() to be consistent with other implementations. Also the manager
may want to add logic to that over time? Maybe not important right now though.

This is how I originally had it, but then this needs to be accessed by
CommandBufferClientImpl::CreateGpuMemoryBufferImage as wel. Mandoline's
CommandBufferClientImpl doesn't have access to MojoGpuMemoryBufferManager since
that's in a different module, so that's why I moved this method implementation
to somewhere else that can be shared.
