[Mac] Middle clicking on home button does not work. It should open home in new

tab. backward button, forward button and reload button have the same problem.

XIB Changes:
* Add ToolbarButton for buttons which should handle middle clicking.
* Switch the home button to be ToolbarButton instead of NSButton.
* Back/forward and reload buttons inherit from ToolbarButton instead of
  NSButton.

BUG=45795
TEST=Middle click on the home button create new tab with home page, or on the
 reload button create new tab with current page. Middle click on the
 back/forward buttons also work with new tab. unit_tests include
 TestbarButtonTest.* suites for testint that.
