[InputControl] Add prefix prop

[adamziel]

Description

This PR adds a prefix property to the InputControl component. The implementation is pretty straightforward - it's just a counterpart of the already existing suffix property. The need was created by the following design from #23375

How has this been tested?

1. Run storybook ( npm run storybook:dev)
2. Navigate to InputControl
3. Play with the prefix property and confirm it works as you'd expect
