Integrate with Windows trust store

[flippingbits]

During our release process, GraalVM captures the trust store from the CI runner and integrates it into the produced native executable. We recently introduced support for custom certificates so that users can configure their own SSL certificates via the extension. This is needed when, for instance, the user sits behind a firewall that performs SSL inspection. Having to configure custom certificates puts a lot of burden on the user.

When running on Windows, the native executable should attempt to use certificates from the Windows trust store so that users don't have to manually add custom certificates to the extension unless they are not part of the Windows trust store.
