backend: Dispatch initial burst of events synchronously on init

Browse Source 
This will consist of device-added events, meaning before init finishes,
we can derive some state that depends on the set of input devices
available on startup, such as cursor visibility.

This avoids cursor visibility switching between hidden and visibility
during startup.
