Use dropdown bar for compact location bar.

 * Refactored CompactLocationBar to Host/View to use DropdownBarHost/View.
 * Changed the logic to show/hide. Per cole's request, losing focus now hides the location bar.
Following features are not implemented yet.
 * Window cripping while animating.
 * Adjust location when toolbar is shown (it's always under tab)
 * clipping autocomplete dropdown.

Timer code is no longer used right now, but is left intentionally as we may put it back.

BUG=None
TEST=None

+// The CompactLocationBarHost implements the container window for the

+// responsible for showing, hiding, closing, and moving the window.
+//
+// There is one CompactLocationBarHost per BrowserView, and its state
+// is updated whenever the selected Tab is changed. The
+// CompactLocationBarHost is created when the BrowserView is attached
+// to the frame's Widget for the first time, and enabled/disabled
+// when the compact navigation bar is toggled.
