Subject: [PATCH] Add granular support for `allowFontScaling` to the `IOText`
 component (#347)

## Short description
This PR adds granular support for the `allowFontScaling` and
`maxFontSizeMultiplier` props to the `IOText` component. This change
alone allows the developer to override these values in the single
instance instead of all instances.

## List of changes proposed in this pull request
- Relax the TS check about `IOText` for the mentioned props

## How to test
Try forcing `allowFontScaling` on the typographic styles, even with the
experimental DS turned off.
