As part of SPM-635, we implemented the necessary changes to support the getClusterParameter command via the embedded router.

In these changes, we introduced the set_cluster_parameter_impl library, which is linked to both the mongos and mongod.

However, this creates an issue because this library has an implicit dependency on mongod_fcv -> feature_compatibility_version_gen, which exposes the featureCompatibilityVersion parameter to the router.

In other words, the mongos now has a concept of FCV and can respond to the command:

db.adminCommand({ getParameter: 1, featureCompatibilityVersion: 1 })

The goal of this ticket is to resolve the incorrect library injection by removing the implicit linking of feature_compatibility_version.idl from the mongos.
