Time applet localization v2

[wiiznokes]

fix #401

previous pr: #429
implement this opened pr: #426

New feature:

• show seconds
• show day name

This PR now use the https://docs.rs/icu/latest/icu/ crate, which is likely to become a standard in the rust ecosystem, as fluent plan to use it.

Know bugs:

• No horizontal bar for vertical layout (i tried but i'm not sure how to proprely implement it anyway)
• The AM is not splited somehow (see seconds screenshot). And splitting it like this is smelly

Design

Some things to consider

• It might be better to make a Tick every second even when we don't show seconds, because users would expect their clock to be somehow reactive a bit.
• icu hourcycle is more exhaustive than the military time boolean
• maybe it's me but compilation time seems to have increase a bit since icu was added, but i have a low end pc so idk

Oh and tracing don't work for me also.

We apparently don't need to translate the weekdays: unicode-org/icu4x#4937

Thanks, this looks mostly good. I've made a few suggestions which fix the issues you were having with the vertical layout.
