Previously, if a header was found via in a header map, and not just remapped. we wouldn't also find the module it maps to when using implicit modules (for module maps that were explicitly loaded). This diff just updates these code paths to also locate the owning module via `findUsableModuleForHeader`. Reviewed By: benlangmuir Differential Revision: https://reviews.llvm.org/D103930
