xsk: add sock_diag interface for AF_XDP
This patch adds the sock_diag interface for querying sockets from user space. Tools like iproute2 ss(8) can use this interface to list open AF_XDP sockets. The user-space ABI is defined in linux/xdp_diag.h and includes netlink request and response structs. The request can query sockets and the response contains socket information about the rings, umems, inode and more.
