build: pass _WIN32_WINNT=0x0601 when building libevent for Windows

This enables of the use of AI_* definitions in the Windows headers,
specifically AI_ADDRCONFIG, which fixes an issue with libevent and
ipv6 on Windows.

It also aligns with what we define in configure when building Core.

# When building for Windows, we set _WIN32_WINNT to target the same Windows
# version as we do in configure. Due to quirks in libevents build system, this
# is also required to enable support for ipv6. See #19375.
