Devices created very late in initialization

[StayTalm]

After the domain reload refactor, devices are not initialized and added until the first update loop.

This means that any initialization code in Monobehaviours (Awake, Start, OnEnable) cannot get access to any devices like the keyboard or mouse until after the first update has passed, which makes for very awkward initialization.

I'm seeing this issue on Mac in the editor but not on Windows.
