Following #14998, reorder the locale segments to `language`, `script`,
`region` to match the standard format. This does not require changes
outside the `Locale` class because `Locale` instances are always
constructed with the `parse` method.

Adjust the rules based on the current codebase. Remove various enable,
disables and default values that are unnecessary. Add more comments
explaining why. Make minor changes needed to enable a few more rules.
Another look at the current Rubocop rules and how they fit with our
existing and desired future style. Almost all of these changes were
automatic. Split some rules between formulae/brew where brew doesn't
have millions of cases that need fixed.
