platform/framework/base: Fix Half Blank screen issue in Wallpaper 

Issue: Start Any Full Screen Activity/ VideoView Activity in
       portrait mode, change to landscape mode and then perform
       suspend and resume. Only Half of the screen has display,
       the other half is blank screen

Fix: Added a check to update surface size on both rotation change
     and surface size change.
