[Mac] Make detached DevTools window draggable by the titlebar - Chrome-side plumbing.

This depends on WebKit change: https://bugs.webkit.org/show_bug.cgi?id=71842

Also, sprinkle OVERRIDE all over devtools_client.h.

BUG=44350
TEST=Open DevTools in undocked mode on the Mac. Drag the window by the empty space in the toolbar. The window should move.
