feat: improve currency type (append local aware curreny name in label)

[Chris53897]

#171

I am not sure what is the best way to implement it.
With this implementation it is an opt-in for the longer labels.

Default

With local currency name (german)

Usage:
->add('currency', CurrencyType::class, ['label' => 'foo', 'currency_choices_label_format' => 1])

Makes sense but maybe you can add constants and documentation for these new options as well? If possible a unit test as well?

[Chris53897]

I can to. Maybe Enum instead of Constants. But maybe i will find a better way to implement it.
getLabel(...) that can be overwritten by the Users. I will need to have a look if this works and is easy to implement.

Another idea is to use placeholders similar to how it works in translations maybe? And we can have:

• %code% to be the currency code
• %name% to be the currency name that you added

And then we can have a string instead to define the format/template to use, and it is very easy to extend maybe? (Default could then be %code% as that is the current default.

Is this something you plan to work on @Chris53897 or should we close it?

[Chris53897]

The earliest possible time for open source work is end of september for me.
I will try to have a look at your placeholder idea.
