IDL: Fix build bugs in IDL dictionary impl generation

IDL: Fix build bugs in IDL dictionary impl generation

- bindings_core_dictionary_impl_generated target should have
  core_dictionary_idl_files as inputs, otherwise IDL dictionaries
  impl classes won't get re-generated when they are edited.
- impl_includes_for_type() should check idl_type.base_type
  (not idl_type.name), otherwise the CG won't include necessary
  header files for nullable interface members.
