[PATCH] D75784: Avoid including Module.h from ExternalASTSource.h

Module.h takes 86ms to parse, mostly parsing the class itself. Avoid it
if possible. ASTContext.h depends on ExternalASTSource.h.

A few NFC changes were needed to make this possible:

- Move ASTSourceDescriptor to Module.h. This needs Module to be complete, and seems more related to modules and AST files than external AST sources.
- Move "import complete" bit from Module* pointer int pair to NextLocalImport pointer. Required because PointerIntPair<Module*,...> requires Module to be complete, and now it may not be.
