This change refactors the top-level dependency scanning flow to follow the following procedure: Scan(): 1. From the source target under scan, query all imported module identifiers for a *Swift* module. Leave unresolved identifiers unresolved. Proceed transitively to build a *Swift* module dependency graph. 2. Take every unresolved import identifier in the graph from (1) and, assuming that it must be a Clang module, dispatch all of them to be queried in-parallel by the scanner's worker pool. 3. Resolve bridging header Clang module dpendencies 4. Resolve all Swift overlay dependencies, relying on all Clang modules collected in (2) and (3) 5. For the source target under scan, use all of the above discovered module dependencies to resolve all cross-import overlay dependencies
