The metadata collector was modified to look up references in the import list instead of resolving the symbol using the TypeChecker making the use of the TypeChecker vestigial. This change removes all uses of the TypeChecker. Modified the schema to be able to record global and local (non-module specific references). Added error messages to the schema and errors are recorded in the metadata file allowing the static reflector to throw errors if an unsupported construct is referenced by metadata. Closes #8966 Fixes #8893 Fixes #8894
