experiment for #148610
This change takes advantage of the fact that
macro_rulescannot be resolved via path-based scope by default1, letting us change their implicit visibility without changing their reach-ability from dependent crates for all existing stable code.TODO
@petrochenkov the PR is split into two commits. The first adds tests that show the current behavior, the second implements the feature, modifies the tests to take advantage of the new feature, and adds a feature gate test.
