Check for display cutout for status bar height

Some devices may have a cutout which increases the height of the status
bar. Use the SystemBarUtil helper class to resolve status bar height
that takes into account display cutout if it exists.

Create a method to resolve caption height from caption height resource
id. This method is overridden for DesktopWindowDecoration to allow it to
use status bar height with cutout when using the default status bar
height id.
