Extensions are currently only supported on linux platforms, since $vectorSearch/$search are only supported on those platforms.

We made some compromises during the implementation phase of extensions based on the assumption that we'll only support linux platforms. However, we may need to provide support for Windows (and perhaps MacOS) in the long term.

Investigate the work required to support extensions on Windows.

todo items:

• GPG was brought into the build system in order to sign our test extensions and import and embed the mongot extension signing key into the server. This was only done for linux platforms. We would need to build gpg for Windows as well, and import it into the build system.
• Extension loading is conditionally compiled in mongod_main.cpp/mongos_main.cpp. Update this to support windows.
