	This removes the pref to re-enable the legacy wizard, and all of the things that used to read from it. It also disables the ability to use the legacy wizard from about:welcome with the aboutWelcomeBehavior feature. It also removes the closeMigrationWizard utility from BrowserTestUtils, since that effectively became a thin-wrapper around BrowserTestUtils.removeTab. Finally, this patch also removes some documentation about the legacy migration wizard, and tests that specifically check the legacy dialog behaviour.
