`std.net.Address.resolveIP` doesn't work on Windows

[phan-do]

Description

std.net.Address can't be (de)serialized atm on Windows due to an issue in resolveIP (I think). Here's a build that failed due to this issue.

How to Reproduce the Bug

In the net_address.zig block files, remove the enclosing if (builtin.os.tag != .windows) statements from the tests and then run the tests on Windows.
