rustdesk eed7052d1d webrtc: declare the ICE policy inside the offer envelope, not a proto field ...

Reverts the webrtc_all_ice proto field (64b54ab) in favor of an
`ice_policy: "all"` key inside the webrtc:// envelope JSON, next to the
RTCSessionDescription fields. Same information, better carrier:

- it is a property of the offer itself, so it rides with the offer;
- the rendezvous server never has to know: the envelope is an opaque,
  length-bounded string to hbbs, so no forwarding code and no vendored
  proto copies to keep in sync;
- serde ignores unknown JSON keys when parsing RTCSessionDescription,
  so every skew combination degrades exactly like the proto field did:
  absence - not an error - is the old Relay-only reading.

endpoint_declares_all_ice() is the receiving side: parse failure,
foreign scheme or missing key all read as "not declared".
