scripts/runfvp: check available terminal types

Browse Source 
Improve usability by detecting which terminal types are available on the
system.

Extend the terminal abstraction to support checking whether a terminal
can be executed, and add basic validation for all terminal types. Update
the documentation to reflect the new behavior.
