py/builtin: Clean up and simplify import_stat and builtin_open config.

The following changes are made:

- If MICROPY_VFS is enabled then mp_vfs_import_stat and mp_vfs_open are
  automatically used for mp_import_stat and mp_builtin_open respectively.

- If MICROPY_PY_IO is enabled then "open" is automatically included in the
  set of builtins, and points to mp_builtin_open_obj.

This helps to clean up and simplify the most common port configuration.
