fix(13.4-01): engine bug fixes — delete strict, super scope, RangeError skip, TDZ skip

- emitter.rs: delete-identifier error now contains "SyntaxError" for negative test matching
- compiler.rs + emitter.rs: add is_arrow param to compile_function_body(_with_bindings);
  non-arrow functions now reset in_derived_constructor/in_instance_method/in_static_method
  to false instead of inheriting parent super flags
- main.rs: remove `e.contains("RangeError")` from non-negative vm-error skip list
- main.rs: remove `e.contains("before initialization")` from compile-error skip list
