[AW][Dev-UI] fix IME issues with search bar

This addresses a few issues I noticed with the IME (AKA "soft keyboard")
with the new search bar:

 * Switches to "adjustPan" mode, which overlays the IME on top of our
   layout rather than resizing our layout to sit above the IME (avoids
   an issue where the bottom nav bar sits above the keyboard)
 * Hide the IME when the user clicks the "done" button
 * Hide the IME when the user taps away from the EditText

Bug: 1052345
Test: Manual - verify IME works as expected
