Support more granular format lengths in `locale`
In #3268 I suggest using the CLDR data to autogenerate locale information. But the current locale data only provides a short and long option. The CLDR data supports four lengths: short, medium, long and full. You can see an example here: https://www.npmjs.com/package/cldr#cldrextractdateformatslocaleidroot-calendaridgregorian
The current locale formats roughly correspond to the short and medium formats in CLDR. I suggest adding the long and full formats as well. Given that banglejs is first and foremost a watch, it makes sense to me that there is extensive support for datetime formats. I can also see that some of the locales use longer formats in the long version. I have mentioned in #3268 that we probably need to make those shorter to ensure compat with apps, but we could still allow apps to explicitly opt in to a longer format by supporting all four CLDR formats.
Because the data is autogenerated from CLDR data, this change can be applied by me for all locales.
I'm not too sure on this... I feel like this is a feature nobody has actually asked for or needed to date?
It's also going to be tricky to do in a backwards compatible way as there's a default Locale built into the Bangle.js firmware
