firebase_auth: verifyPhoneNumber should not sign in #22304
Description
I want to link phone number to my user's account.
But I can't as verifyPhoneNumber implicitly signs in on native side.

To be consistent with other methods, it should instead return Future<sms code>, and report verificationId with callback as it might be expired while waiting for the code sent.
///
Future<String> verifyPhoneNumber({
@required String phoneNumber,
@required Duration timeout,
int forceResendingToken,
@required PhoneCodeSent codeSent,
@required PhoneCodeAutoRetrievalTimeout codeAutoRetrievalTimeout,
}) async {}
Future<FirebaseUser> signInWithPhoneNumber({
@required String verificationId,
@required String smsCode,
}) async {}
Future<FirebaseUser> linkWithPhoneNumber({
@required String verificationId,
@required String smsCode,
}) async {But this is breaking change.
