Trigger re-inflation when configuration changed

We re-inflate the layout when font or display size are scaled and do
follow fixes:
1. Listen to CONFIG_FONT_SCALE and CONFIG_DENSITY for layout
   re-inflaction.
2. Remove the configurations of image button and Done button paddings,
   and set the size of icons and center the text directly so the
   contents instead of the paddings inside the button will scale up when
   we increase the display size.
3. Reconstruct the layout to guarantee all components will stay in the
   settings panel without being cut.
