feat: Re-implement wrap-websocket into agent

[ellisong]

Re-implement wrap-websocket code using ES6 extends syntax into the agent. This will allow supportability metrics to be reportable from websocket API usage.

Overview

We're re-implementing the wrap-websocket code into the agent that was taken out in 1.265.1 patch to address deploy issues. The new implementation uses ES6 extends syntax to include static class constants and all the properties of the original WebSocket object. Tests are included that cover usage with the third-party libraries robust-websocket and reconnecting-websocket.

General reminder that this is a high-risk feature. Should be deployed on its own and undergo more scrutiny before deployment
