Rename "Path-Based Scope" section title

This renames the section title to "The `macro_export` attribute" to
follow the attribute template. Although I like the old title, since it
describes what it does, I would prefer to not make exceptions and stay
consistent.

 By default, a macro has no path-based scope. However, if it has the `#[macro_export]` attribute, then it is declared in the crate root scope and can be referred to normally as such:
+r[macro.decl.scope.macro_export.intro]
