Remove deprecated code from `Runtime` object

This removes all the core code that called the pre-`KeyEvent` hook functions
`onKeyswitchEvent(key, addr, state)` and `beforeReportingState()`.  Any plugins
that were still using these functions should use the newer equivalents instead:
`onKeyEvent(event)` & `beforeReportingState(event)`.
