Adds SO_UNICAST_RECEIVE_SHARING to the SOL_SOCKET socket options table and platform-support table.

Covers:

  • Shared-unicast delivery semantics on datagram sockets.
  • Pre-bind requirement and mutual exclusion with SO_EXCLUSIVEADDRUSE / SO_REUSE_MULTICASTPORT / SIO_CPU_AFFINITY.
  • Per-socket runtime feature detection via a getsockopt probe.

Companion to the sdk-api documentation update adding the WSAGetUnicastReceiveSharing / WSASetUnicastReceiveSharing wrapper pages.
