quic: multiple updates to quic impl

* separate stats and symbols into separate files
* quic: rename `EndpointStats` and `SessionStats` to be consistent
  * s/EndpointStats/QuicEndpointStats/
  * s/SessionStats/QuicSessionStats/
* separate state into separate files and other cleanups
* extend tls options validations
* rename classes for consistency and other cleanups
