Add support for SO_REUSEADDR to UDP sockets/endpoints.
On UDP sockets, SO_REUSEADDR allows multiple sockets to bind to the same address, but only delivers packets to the most recently bound socket. This differs from the behavior of SO_REUSEADDR on TCP sockets. SO_REUSEADDR for TCP sockets will likely need an almost completely independent implementation. SO_REUSEADDR has some odd interactions with the similar SO_REUSEPORT. These interactions are tested fairly extensively and all but one particularly odd one (that honestly seems like a bug) behave the same on gVisor and Linux. PiperOrigin-RevId: 315844832
