  Support <link rel=dns-prefetch> on iOS and remove privacy-invasive DNS prefetching features
https://bugs.webkit.org/show_bug.cgi?id=285744
rdar://144699889

Reviewed by Alex Christensen.

This was initially landed as 288915 at main and backed out in 288920 at main
because it was not understood all functionality was enabled for macOS.

This commit wants to reland 288915 at main as-is, but now with the
understanding that this removes privacy-invasive and proprietary DNS
prefetching features from macOS, while continuing to support the
standardized <link rel=dns-prefetch> and extending that support to iOS
and other WebKit ports.
