[NUI] Add font thread sync creation option

If sync creation is true, font thread creation guarantees syncronization with the main thread.

The main thread runs the font thread and waits,
and it wakes up upon receiving a notification from the font thread.
If it doesn't receive a notification within the specified time, it wakes up due to a timeout.
