Trailing zeros should never be added

[michaelkeeling]

The addTrailingZeros method in abstract-number-format-input is redundant and overrides default and expected behaviors already provided by the formatter. If a user wanted trailing zeros, then they can set the minimumSignificantDigits option. Intl.NumberFormat will truncate zeros when the number of fractional digits is less than maximumFractionDigits and this component should honor that behavior.

var number = 123.456;

formatter = new Intl.NumberFormat("en-US", { style: 'decimal', minimumSignificantDigits: 20 });
console.log(formatter.format(number))

// "123.45600000000000000"

formatter = new Intl.NumberFormat("en-US", { style: 'decimal', maximumFractionDigits: 20 });
console.log(formatter.format(number))

// "123.456"
