As part of SERVER-99302, a new API has been implemented for binary-compatible feature flags. However, in order to avoid needing to refactor all usages across the codebase in the same ticket as the API changes, some stubs have been provided.

The purpose of this this PR ticket is to do a mass replacement of all binary-compatible feature flag checks to call FeatureFlagBinaryCompatible::isEnabled(void) and remove those compatibility stubs.
