[Mac] Don't change state from stop to reload when hovered.

Hold the reload button state change from stop to reload until the
mouse exits.  Also short-circuit the stop message when the real state
should be reload.  Also prevent multi-clicks from sending multiple
actions.

Toolbar.xib: reload button made kind of ReloadButton.

BUG=47184
TEST=Browse to a slow page, mouse over stop button.  Should not go to reload button when throbber (in tab) stops.
TEST=After page loaded, click stop.  Should not crash.
TEST=Hover over reload button.  Command-r should start a reload and change the button to stop button.
