feat: create number formatting component

What this does

This PR adds a component to format numbers in a consistent way. The intention is to centralise the logic for formatting numbers that lives in t-big-number, into a simple component. This will allow report authors to get consistent number formatting wherever they use this component. It will replace the logic in t-big-number in a separate PR.

This component will format the number to the 'en' locale until it reaches a threshold, and then it will be formatted using the 'compact' notation.
