both timezones and locales have aliases (either thru deprecation/migration/etc.)
for locales we compile a mapping, for timezones we dont. yet we can benefit partial alias support thru DateTimeZone, which knows about most timezone IDs already.
both the timezone + locale validator already support aliases. Connsequently, we should support aliases in `Timezones::exists()` + `Locales::exists()` as well IMHO.
so far so good; the catch is; with this PR `Locales::getName()` supports aliases, whereas `Timezones::getName()` doesnt. I think it's reasonable for now, until we compile the timezone mapping so we can widen the timezone ID conversion here.
