Make caption a insets source
This patch introduced setCaptionInsets, and set the Insets in
ViewRootImpl when dispatch the insets if there's a caption.
Modification is made in Window and DecorCaptionView to make caption
overlay with the app content, and pass the value to ViewRootImpl to
apply when dispatch. It is necessary to trigger a dispatch when caption
enabled status chanaged, otherwise sometimes it will not be updated.
Because caption is now updated locally on the client side.
Some old logic to deal with the overlay caption without insets are
removed, including the touch event dispatch override, the color
override.
