Found a reliable way to return default system DNS resolvers on iOS and
macOS. Even if this method is not perfect, I think it's still worth
pursuing because:

* Many administrators will set an upstream resolver in the portal anyway
(bypassing client system resolvers)
* It unifies our Split DNS approach across platforms (assuming we can
query the default system resolvers on Windows), allowing connlib to
intercept all DNS queries on all platforms. This opens the door for some
interesting feature possibilities in the area of malicious query
blocking. This also makes DNS bugs easier to investigate because there's
only one codepath for packets to take. See
https://github.com/firezone/firezone/issues/2859

Draft because it needs more testing and I need to figure out the
`RustVec<RustString>` type for the Swift -> Rust FFI.
