Replace locale_config

[bGVia3VjaGVu]

I think locale_config is abandoned . It uses the regex crate with all default features enabled for parsing locale. So there won't be any features for reducing compile times and binary sizes. https://github.com/rust-locale/locale_config/pull/13 https://github.com/rust-locale/locale_config/pull/8

There's a potential to replace it with sys-locale as per https://github.com/kellpossible/cargo-i18n/issues/63#issuecomment-2340093419 I'm open to any contributions to do so.

I've made a hard fork https://github.com/eirtools/locale_config with various fixes
