Fix Form Field Controls layer height from 20px to `size-base`

[amritadesmet]

Issue: in Figma, Radio group, Checkbox and Switch controls in Form Field all use spacing 20px hardcoded rather than the size-base token. The Input control is using size-base. We shouldn't be using hard coded values. This needs to be adjusted for both Top and Left variants of FF.

Solution:

• Change Radio group Control layer height to size-base
• Change Checkbox Control layer height to size-base
• Change Switch Control layer height to size-base
