Netplay netpacket connection flow improvements (#15986) 
- Allow starting netplay host while a netpacket core is running without restart
- Allow connecting to a host while a netpacket core is running without restart
- Avoid clients getting stuck in connection loop if the host has the content paused while a client connects by automatically unpausing
