Reviewed by Aditya Keerthi.

Add a missing 390pt screen dimension breakpoint when advanced privacy protections are enabled;
currently, this causes some websites that rely on the screen width for layout to assume that the
width of the page is larger than it actually is.

* Source/WebKit/WebProcess/WebPage/ios/WebPageIOS.mm:
(WebKit::WebPage::screenSizeForFingerprintingProtections const):
* Tools/TestWebKitAPI/Tests/WebKit/AdvancedPrivacyProtections.mm:

Also, augment an existing API test to verify that the new screen size breakpoint behaves as
expected.
