DO NOT MERGE Allow windows to show when input restricted.

Allows non-activity windows to show instead of being hidden (e.g IME)
when lock screen is not showing. This is a difference from current
behavior in G when:

  1. The device is not interactive (either of AoD-on/-off).
  2. The device is interactive and isInputRestricted is true.

This allows for consistency w/ activity manager on allowing IME to be
visible whenever an activity is allowed to be visible (w/o special flags).
