Add Wasm testing in Chromium, not just command-line `v8` (#40786)

This should give us a better idea of any cases where browser and JS engine behaviour diverge.

* Uses WebSockets to write pipe console messages to the test runner.

* Skip System.Net.Http FunctionalTests depending on X509 certificates, tests discovery fails on `System.Net.Http.Functional.Tests.HttpClientEKUTest..cctor()` which ends up throwing PNSE

* Added environment variable to help platform detect when we're running in the browser vs v8

* System.Net.Http LoopbackServer: fix NullReferenceException because we were trying to dispose a Socket instance that threw PNSE in the constructor
