[Dependency Scanning] Do not add cross-import overlays that involve the main module being scanned

Browse Source 
For example, when scanning a source module `Foo`, which, when depending on module `Bar` causes a cross-import overlay `_Foo_Bar` to be added, do not add this cross-import overlay when scanning `Foo` itself. For example, if `Foo` adds a dependency on `Bar` itself in its own dependency graph.
