fix(common): round currencies based on decimal digits in CurrencyPipe (#21783)

Browse Source 
By default, we now round currencies based on the number of decimal digits available for that currency instead of using the rouding defined in the number formats.
More info about that can be found in http://www.unicode.org/cldr/charts/latest/supplemental/detailed_territory_currency_information.html#format_info

Fixes #10189
