In RFP mode, we do not support `PerformanceNavigationTiming`, so don't expose it. In particular, `window.PerformanceNavigationTiming` should return `undefined`. Added a new method `PerformanceNavigationTiming::Enabled` which when used with the WebIDL `Func` attribute allows us to toggle whether `window.PerformanceNavigationTiming` is exposed. Created `dom/tests/mochitest/general/test_toggling_performance_navigation_timing.html` to test whether the toggling works. Updated `browser/components/resistfingerprinting/test/browser/browser_performanceAPI.js` to create a new window each time `privacy.resistFingerprinting` is flipped so this behavior does not leak into other tests. Differential Revision: https://phabricator.services.mozilla.com/D73528
