Add shared lib core windows

[edif2008]

📋 Summary

This PR enables the Go SDK to interact with the 1Password app on Windows.

🤔 Thought process

Using the golang.org/x/sys is common for this specific use case, so I relied on that package to make this. It's latest version updated our SDK to be built using Go 1.24, which is great given that this is a supported version right below the latest one (1.25).

🧪 How to test

1. Run 1Password app on nightly on Windows and enable the internal feature flag for the SDKs for Desktop integrations.
2. Checkout this branch.
3. Update the account name in the example/desktop_app/main.go file.
4. Export the OP_VAULT_ID and OP_GROUP_ID environment variables.
5. Run the example program:

   go run example/desktop_app/main.go

   • It should prompt to authorize the SDK via the 1Password app
   • It should perform all the operations in the program successfully.
