Disable max WebSocket message size validation in CDP proxy (facebook#39833)

Summary:

Reland of D49642047 which got reverted because of a CI infra error.

---

It's currently possible for RN to crash the dev server by sending down an exceptionally large CDP response/event. Instead of making assumptions on the protocol spoken over the proxy, let's assume clients on either side of the proxy can be trusted to be well behaved (and to degrade gracefully when a large message is encountered).
