Replaces the previous `export/saveEntriesFn` split with a stricly more general function such that `exportEntriesFn` could be deprecated at a later point. Also gives the new function access to the `Environment` while we're at it. Also gives `getModuleEntries` access to more olean levels in preparation for `meta import`.
