views: Add support for absolute positioned overlay views.

Browse Source 
To test:
Run `cefclient.exe --use-views --hide-frame --hide-controls`
Add `--enable-chrome-runtime` for the same behavior using the Chrome location
bar instead of a text field.

// Add a View that will be overlayed on the Window contents with absolute
// positioning and high z-order. Positioning is controlled by |docking_mode|
// as described below. The returned CefOverlayController object is used to
// control the overlay. Overlays are hidden by default.
//
// With CEF_DOCKING_MODE_CUSTOM:
// 1. The overlay is initially hidden, sized to |view|'s preferred size, and
// positioned in the top-left corner.
// 2. Optionally change the overlay position and/or size by calling
// CefOverlayController methods.
// 3. Call CefOverlayController::SetVisible(true) to show the overlay.
// 4. The overlay will be automatically re-sized if |view|'s layout changes.
// Optionally change the overlay position and/or size when
// OnLayoutChanged is called on the Window's delegate to indicate a
// change in Window bounds.
//
// With other docking modes:
// 1. The overlay is initially hidden, sized to |view|'s preferred size, and
// positioned based on |docking_mode|.
// 2. Call CefOverlayController::SetVisible(true) to show the overlay.
// 3. The overlay will be automatically re-sized if |view|'s layout changes
// and re-positioned as appropriate when the Window resizes.
//
// Overlays created by this method will receive a higher z-order then any
// child Views added previously. It is therefore recommended to call this
// method last after all other child Views have been added so that the overlay
// displays as the top-most child of the Window.
