Settings: Remove unnecessary GetHelpUrlWithBoard() helper.

This function attached a parameter to help URLs on ChromeOS which could
potentially display different help content based an a CrOS device's
board info. This is not relevant after the OS/Browser settings split,
since device specific settings no longer reside in chrome://settings.
