[PHP] Fix UDP sockets for PHP v8

[zeroSteiner]

So in my last PR #786 I fixed UDP channels for PHP 5.3.29 by prioritizing using sockets instead of streams. This then broke things on PHP v8 where sockets are not resources and thus treating them in the same way was causing a whole bunch of issues. This resolves those issues so the socket tests that are intended to pass do pass with both PHP v8.4 on Linux and PHP v5.3 on Winows.

At this point in time, this is a "successful" pass of the socket channel tests:

Server channels fail because there's no TCP server channel support (see rapid7/metasploit-framework#20748) and the UDP peer addres is a rex socket issue.
