dev: Refactor UART->Terminal interface

The UART models currently assume that they are always wired to a
terminal. While true at the moment, this isn't necessarily a valid
assumption. This change introduces the SerialDevice class that defines
the interface for serial devices. Currently, Terminal is the only
class that implements this interface.
