feat: allow UART expectations written in LAVA job YAML format

This change introduces the ability to use the LAVA job YAML format
directly instead of the existing Bash Expect-like scripts, which saves
us from having to invent a new syntax to deal with anything that is
currently unsupported (like timeouts).
