[SxS] Add (non-functional) resize handle

Creates a MultiContentsResizeArea class which is visually similar to the
side panel's resize area. This can respond to left/right keyboard events
to resize as well as mouse click+drag, and has a keyboard focusable
icon. Currently emits events to a stubbed out OnResize method, will
implement this in a follow-up to actually resize the WebContents as
relative to each other.
