WM: Event simulation support for Python

Browse Source 
This feature is intended only for testing,
to automate simulating user input.

- Enabled by '--enable-event-simulate'.
- Disables handling all real input events.
- Access by calling `Window.event_simulate(..)`
- Disabling `bpy.app.use_event_simulate`
  to allow handling real events (can only disable).

Currently only mouse & keyboard events work well,
NDOF, IME... etc could be added as needed.

See D4286 for example usage.
