Frameworks: Lockscreen Blur

  If user selects "See through" under screen security,
  the locksceen background will now appear transparent
  with the content behind it blurred.

Modificaitons made to the orginal commit to support Hammerhead and Flo.
It seems full HD images causes rendering artifacts. To prevent this,
we scale the image size to something more manageable.

PS2: Reduce calls to System.Settngs
     Move bitmap scaling to DisplayPowerController
PS3: Fix styling
PS4: Fixes: 1. Black wallpaper after turning off see through
            2. Wallpaper flicker on unlock when blur is enabled
PS5: Ignore status bar and nav bar when capturing screenshots
PS6: 1. Remove content observer and unnecessary calls from viewManager
     2. Restructure the flow of setting the custom image
         * now closely follows setting album art as lockscreen image

Fix: Ensure lockscreen see through setting persists after reboot

If see through was enabled and the device was rebooted,
the user had to toggle the setting off and on again to activate.

Keaguard: enable translucent keyguard by default

currently it is possible to enable it per device over an overlay and it is disabled
by default. Enable it by default but respect general transluscent disable from
device tree. Manta eg disables this feature due of graphical glichtes.
