Use the same TcpSocket in WASIp{2,3} (#11386)

* Use the same `TcpSocket` in WASIp{2,3}

This is the same as #11384 except for `TcpSocket` to share the
implementation of TCP across WASIp{2,3} and avoid duplicating code
between the two.

* Fix CI issues

* Review comments

* Trim "TCP allowed?" checks

Like UDP only perform the check on socket creation, not after it's
created.
