In existing Swift, an `@_exported import` in any source file makes the declarations from the imported module visible in all source files. It's unclear whether this is an explicit decision or is simply and unintended consequence of effectively adding an implicit import to each source file for the module being compiled. Although it's not clear whether this behavior is desirable, the behavior of member lookup when the MemberImportVisibility feature is enabled should align with it in order to avoid causing unnecessary churn in required imports. Resolves rdar://132525152.
