Exposing HTTP/2 and HTTP/3 protocol error details from SocketsHttpHandler

This proposal builds on the decisions made in our QUIC Exceptions Design proposal.

Proposed design

• Define a new exception type ProtocolException, and embed it as HttpRequestException.InnerException
• Throw ProtocolException directly from HttpResponse content read streams
• In case of HTTP/3, embed QuicException as ProtocolException.InnerException
