SPIKE - Consider clearer loader names

[kquerna]

Description

Currently, we use LocaleRequired in our component, HOC, and hook to load translated/localized files. The current name can yield a bit of confusion, since you are not loading a locale, but rather a localized message file. Technically, locale is required, which determines which version of the translated file to load, but the purpose of the components is to specify which translated file.

So, instead of withLocaleRequired, should we change these to be withTranslation, or withLocalizedFile, or withLocaleMessages?
