Made the registration and deletion of transfer buffers async.
Added a thread safe way to duplicate a shared memory handle for the GPU process.
Removed synchronous IPC to set the command buffer shared state buffer.
Removed CreateTransferBuffer IPC. Removed request_id arg from transfer buffer IPCs. It wasn't being used.
