Investigate ref forwarding for inputs and controls.

[wmui51]

See if we can add ref forwarding for input/control components:

• Checkbox - https://github.com/Autodesk/hig/pull/2390
• Dropdown
• Input - https://github.com/Autodesk/hig/issues/2261
• RadioButton
• Slider - https://github.com/Autodesk/hig/pull/2391
• TextArea - https://github.com/Autodesk/hig/issues/2331
• Toggle
• NumericInput

This has been done on the Input we should follow that pattern for the rest of the inputs and controls.
