Support live formatting in NumberField

### Provide a general summary of the feature here

I would be very nice to enable live formatting in the RAC NumberField component.

### 🤔 Expected Behavior?

When a user types the value is formatted while typing.

### 😯 Current Behavior

The value is currently only formatted when a user blurs (click outside/tab out) the input.

### 💁 Possible Solution

I would expected this to be the default behavior. But I imagine some developers would like to turn it off. So either a prop `liveFormatting?: boolean` or a prop `noLiveFormatting?: boolean`.

### 🔦 Context

When inputing large numbers (such as when a customer is applying for a loan at a bank), it is much easier for a user to read:
11 500 000, than 11500000 while typing.
