Add support to BRL (Brazilian) currency

There are currently only 8 currencies supported.
I'd like to use brazilian which uses R$ or BRL instead of a currency symbol (such as $).

We would also be ok with specifying R$ or BRL as the suffix.

We're currently rolling out a new Number Input with support for any currency code! The default symbol and formatting will depend on your browser and locale, but you can also override the defaults with updated prefix/suffix fields that no longer have a character limit.

If you don't see the Number Input in the component list yet, check back in a few days. We should be fully rolled out sometime next week.

Check out the changelog for more details.
