feat(data-forwarding): add padding prop to FieldLayout components (#108803)

Adds an optional `padding` prop to `FieldLayout.Row` and
`FieldLayout.Stack` in
`static/app/components/core/form/layout/index.tsx`.

Needed by the data forwarding form migration (follow-up PRs) where form
fields rendered inside a `Disclosure` require padding to match the
surrounding layout.

Since these are layout components, I think it is reasonable for us to
forward the props
