Expand mypyc module compilation to 36 modules

Add 22 more modules to mypyc compilation for better performance:

Type system:
- assert_name.py

Language/parsing:
- source.py, location.py, token_kind.py
- directive_locations.py, print_string.py

Utilities:
- type_info.py

Execution:
- build_field_plan.py, types.py

Error handling:
- graphql_error.py, located_error.py

Pyutils (hot paths):
- path.py, is_awaitable.py, is_iterable.py
- gather_with_cancel.py, async_reduce.py
- ref_map.py, convert_case.py, suggestion_list.py

Validation:
- validate.py, validation_context.py

All 36 modules compile successfully with mypyc.
