LibVT: Make TerminalWidget's automatic size policy updates optional

Browse source 
When embedding a TerminalWidget, you might not want it to automatically
update its own size policy based on the exact terminal buffer size.

This behavior is now passed as a flag to the TerminalWidget constructor
which makes it behave nicely both inside HackStudio and in Terminal.
