    Initial support for in-display fingerprint sensors

    * Initially based upon phh's Mi9 implementation,
      however a lot of changes have been made since.
    * All device specific stuff has been moved to
      IFingerprintInscreen HIDL interface and most
      of code has been improved and refactored.

    FODCircleView: defer removal to next re-layout

    * Originally, when hide() is called, it removes the dim layer and then
      removes the view immediately, then calls the hide event in HAL. This
      causes severe flickering because the HAL is expected to restore the
      brightness immediately, but the dim layer will not be removed until
      the next repaint cycle.

    * Since it is not easy to listen for a redraw after the view itself has
      been removed, we can defer removal after the next time onLayout() is
      called. When tested on my OnePlus 7 Pro, this reduces flickering on
      successful fp authentication drastically.

    * There are some cases where show() is called so quickly after hide()
      that the view hasn't been actually removed due to this change (which
      is actually another cause of flickering). This is handled by checking
      the removal flag in show() and removing it immediately if the view is
      yet to be removed, and also by moving calls to HAL show / hide events
      to the actual attached / detached event handlers.

    * For consistency in semantics, also move calls related to the dim
      layer that were originally in onDraw for similar reasons to the
      onLayout function.

    FODCircleView: place above other UI elements

    The navigation bar used to appear brighter because
    TYPE_VOLUME_OVERLAY is behind TYPE_NAVIGATION_BAR.
    Move the FOD overlay to TYPE_DISPLAY_OVERLAY
    to be above other UI elements.

    KeyguardView: report transiting bouncer as shown

    FOD icon is shown until after the bouncer animation
    is completed because onKeyguardBouncerChanged isn't
    called when the bouncher animation is started.
    Call updateStates when starting to show bouncer
    and make sure a transitioning bouncer is considered
    shown to make the FOD icon dissapear without
    overlapping bouncer.

    FODCircleView: Show while bouncer is requesting Pattern or PIN

    Also allow devices to overlay the minimum bottom padding of the
    keyguard security container so that they may shift the pattern/pin input
    and the emergency call button up until the FOD icon does not obscure the
    view.
