fix: disable Arrow S3 on Windows to avoid OpenSSL dependency

Arrow S3 requires AWS SDK which depends on OpenSSL::Crypto, but OpenSSL
is not available on Windows builds. This mirrors how curl.cmake already
uses Schannel instead of OpenSSL on Windows. S3 support remains enabled
on Linux/macOS.

Fixes #178
