Take the input device into account for meta state

Interesting nits about this:
- getMetaState(long) and getMetaState(long, int) do not
  seem to be used anywhere in the framework. Maybe we
  want to skip adding getMetaState(long, KeyEvent) and
  getMetaState(long, int, KeyEvent).
- getMetaState(CharSequence, int) is used extensively
  throughout the code. In some places, a KeyEvent is
  available and should be considered - this change does
  implement this. In many other cases, there is no
  relevant KeyEvent for this action (for example,
  Editor#extractTextInternal). In these cases, the
  behavior is affected by the current latch state, so
  it's fine to leave them as is.
