Allow UDP to bind to the same ip/port

[TrentHouliston]

This pull request refactors how socket options are set for UDP sockets, improving consistency and reliability in both the main UDP implementation and the emit path. The changes focus on ensuring proper reuse of addresses and ports, and on clarifying when broadcast options are set.

Pull Request Overview

This PR enables UDP sockets to bind to the same IP address and port combination by adding socket reuse options. The changes allow multiple UDP sockets to share the same address/port, which is useful for scenarios like load balancing or multiple listeners.

• Adds SO_REUSEADDR and SO_REUSEPORT socket options to UDP emit functionality
• Removes conditional logic that previously restricted reuse options to only broadcast/multicast
• Removes duplicate broadcast socket option setting

• The variable yes is being used but was not declared in this scope after removing the conditional block. The variable declaration needs to be added before this line.
