Simplify IME policy and enforce in binder calls. Revert the overly complicated bc7b6fc2a4b701596a2c8eecc4aeef522abeeafa. Since setImeWindowStatus can be called externally, enforce similar keyguard policy so that this is not a backdoor for IMEs bound under the keyguard to drive IME visibility. Policy is simplified, we keep track of whether the keyguard is locked when the current IME switches. This fixes b/7498792 (activity under lockscreen drives IME visibility when lockscreen is rotated) and does not break b/11186297 (IME visible when BT keyboard is attached).
