  [clang][Dependency Scanning] Report What a Module Exports during Scanning (#137421)

We would like to report, for a module, which direct dependencies it
exports during dependency scanning. This PR implements this reporting by
augmenting `ModuleDep`'s `ClangModuleDeps` variable. `ClangModuleDeps`
now contains instances of `DepInfo`, which is made of a `ModuleID` and a
boolean flag that indicates if a particular dependence is exported.
