SystemTask state refactor

[mark9064]

Currently SystemTask is somewhat fragile to duplicate state transitions and unusual state transition message orders. Most notably this can cause it to get stuck in GoingToSleep in some scenarios.

This PR introduces GoToSleep() and changes GoToRunning() as immediately executable functions. The guarantee that state transitions happen immediately reduces complexity when it comes to ensuring the device is awake for events such as Chimes

Fixes part of #1790 #2012 (there may be other issues contributing to these, but this is probably part of it)
