Eliot Courtney c3bd240f97 gpu: nova-core: gsp: add reply/no-reply info to CommandToGsp
Add type infrastructure to know what reply is expected from each
`CommandToGsp`. Uses a marker type `NoReply` which does not implement
`MessageFromGsp` to mark commands which don't expect a response.

Update `send_command` to wait for a reply and add `send_command_no_wait`
which sends a command that has no reply, without blocking.

This prepares for adding locking to the queue.
