MITM: Allow using local received SNI in the outgoing serverName & verifyPeerCertInNames

Browse source 
https://github.com/XTLS/Xray-core/issues/4348#issuecomment-2637370175

Local received SNI was sent by browser/app.

In freedom RAW's `tlsSettings`, set `"serverName": "fromMitm"` to forward it to the real website.

In freedom RAW's `tlsSettings`, set `"verifyPeerCertInNames": ["fromMitm"]` to use all possible names to verify the certificate.
