gfe-relnote: Add QuicUdpSocketApi, a de-platformized version of QuicSocketUtils, and use it in some non-production code. No behavior change, not protected.

This is the first step to kill quic_socket_utils.(h|cc).

Chromium merge notes:
1) The platform impl function, GetGooglePacketHeadersFromControlMessageImpl, can simply return false.
2) Please add quic/core/quic_udp_socket* to "epoll_quic_tools" in BUILD.gn: http://shortn/_zpf4caOcsa
