LibGUI: Make focus events more aware of why focus is changing

Browse source 
This patch adds GUI::FocusEvent which has a GUI::FocusSource.
The focus source is one of three things:

- Programmatic
- Mouse
- Keyboard

This allows receivers of focus events to implement different behaviors
depending on how they receive/lose focus.
