Browser WebSockets tests

[lewing]

We still don't have good functional tests for browser WebSockets in CI in inner or outer loops as evidenced by #44551 we need to resolve this now that we are unblocked on the xharness side.

• Partial send {endOfMessage: false} System.Net.WebSockets.Client.Tests.SendReceiveTest.SendReceive_PartialMessageDueToSmallReceiveBuffer_Success
• Text/Binary System.Net.WebSockets.Client.Tests.ConnectTest.EchoBinaryMessage_Success, EchoTextMessage_Success
• Cancellation System.Net.WebSockets.Client.Tests.CancelTest
• Abort System.Net.WebSockets.Client.Tests.AbortTest
• SendAsync buffering/completion System.Net.WebSockets.Client.Tests.ArraySegmentSendReceiveTest
