Subject: [PATCH] units: Re-order impl_parse_str

We have a public macro `impl_parse_str` and a helper macro used by it,
both pubicly exported.

As we did for `impl_parse_str_from_int_infallible`; to assist readers
understanding what is going on put the helper below the other.

Done as a separate patch to make the diff easier to read.

Internal change only, no logic change.
