net: fix panic when calling net.Listen or net.Dial on wasip1
Address a panic that was caused by net.Dial/net.Listen entering the fake
network stack and assuming that the addresses would be of type *TCPAddr,
where in fact they could have been *UDPAddr or *UnixAddr as well.
The fix consist in implementing the fake network facility for udp and
unix addresses, preventing the assumed type assertion to TCPAddr from
triggering a panic. New tests are added to verify that using the fake
network from the exported functions of the net package satisfies the
minimal requirement of being able to create a listener and establish a
connection for all the supported network types.
