With this we implement DNS forwarding that's specified in #2043 This also solve the DNS story in Android. For the headless client in Linux we still need to implement split dns, but we can make do with this, specially, we can read from resolvconf and use the forward DNS (not ideal but can work if we want a beta headless client). For the resolver I used `trusted-proto-resolver`. The other options were: * Using `domain`'s resolver but while it could work for now, it's no ideal for this since it doesn't support DoH or DoT and doesn't provide us with a DNS cache. * Using `trusted-proto-client`, it doesn't provide us with a DNS cache, though we could eventually replace it since it provides a way to access the underlying buffer which could make our code a bit simpler. * Writing our own. While we could make the API ideal, this is too much work for beta. @pratikvelani I did some refactor in the kotlin side so we can return an array of bytearrays so that we don't require parsing on connlib side, I also tried to make the dns server detector a bit simpler please take a look it's my first time doing kotlin @thomaseizinger please take a look specially at the first commit, I tried to integrate with the `poll_events` and the `ClientState`.
Connlib
Firezone's connectivity library shared by all clients.

Building Connlib
Setting the CONNLIB_MOCK environment variable when packaging for Apple or Android will activate the mock feature flag, replacing connlib's normal connection logic with a mock for testing purposes.
- You'll need a Rust toolchain installed if you don't have one already. We recommend following the instructions at https://rustup.rs.
rustup showwill install all needed targets since they are added torust-toolchain.toml.- Follow the relevant instructions for your platform:
- Apple
- Android
- Linux
- Windows
Apple
Connlib should build successfully with recent macOS and Xcode versions assuming you have Rust installed. If not, open a PR with the notes you found.
