The generator will look for IDL files recursively in these include dirs (using
File::Find in perl). The issue was that the include dirs were very specific and
incomplete. Therefore, some IDL interfaces could not be resolved.

We could just make add the missing dirs but I decided to include top-level dirs
instead so that we don't need to update this list all the time.

             '--include', '<(SHARED_INTERMEDIATE_DIR)/webkit',
           ],
         },
