@NgModule()s get compiled to two fields: ngModuleDef and ngInjectorDef.
Both fields contain imports, as both selector scopes and injectors have
the concept of composed units of configuration. Previously these fields
were generated by static resolution of imports and exports in metadata.
Support for ModuleWithProviders requires they be generated differently.
ngModuleDef's imports/exports are generated as resolved lists of types,
whereas ngInjectorDef's imports should reflect the raw expressions that
the developer wrote in the metadata.
This change modifies the NgModule handler and properly copies raw nodes
for the imports and exports into the ngInjectorDef.
