DataViews: vendor ValidatedToggleControl

[oandregal]

Part of #81230
Follow-up to #81391, #81433, #81434, #81435, #81449, #81450, #81451

What?

Vendors ValidatedToggleControl into @wordpress/dataviews as an internal component, and removes it from the @wordpress/components private APIs.

Why?

See #81230

How?

• Adds packages/dataviews/src/components/validated-form-controls/toggle-control.tsx, wrapping the public ToggleControl from @wordpress/components with the already-vendored ControlWithError. Behavior is preserved exactly.

Testing Instructions

1. npm run test:unit -- packages/dataviews/src/components/validated-form-controls/test/toggle-control.tsx — passes.
2. npm run storybook:dev, then open DataViews → DataForm → Validation.
3. Enable the toggle field in the story controls and mark it required.
4. Try to submit without activating the toggle: the validation error message appears, wired to the control via aria-describedby.
5. Activate the toggle: the error clears and the form submits.
