Fixes #165445. Fixes a crash when `ASTWriter::GenerateNameLookupTable` processes enum constants from C++20 header units. The special handling for enum constants, introduced in fccc6ee, doesn't account for declarations whose owning module is a C++20 header unit. It calls `isNamedModule()` on the result of `getTopLevelOwningNamedModule()`, which returns null for header units, causing a null pointer dereference.
