[IDE][DocSupport] Fix DocInfo missing decls when generated for clang submodules.

Browse Source 
Out handling of clang submodules was handled differently between DocInfo and
InterfaceGen. For InterfaceGen submodules were mapped back to their top-level
clang modules (or their Swift overlay if it had one) before being passed
into printSubmoduleInterface, along with the dot separated name of the submodule.

For DocInfo, they were not, and only the rightmost component of their name was
passed. The call to retrieve the decls from a ModuleDecl doesn't work if the
ModuleDecl wraps a clang submodule, so we were missing these decls.

InterfaceGen for submodules also shouldn't have been mapping the module back to
the overlay of top-level clang module, as that meant we ended up printing
import decls from the Swift overlay in the submodule's interface.
