Editor: Restore static properties for deprecated __experimentalLinkControl.

[59775] resulted in a backwards compatibility break in a now deprecated experimental component, which was stabilized to `LinkControl`. When experimental components are deprecated in favor of being stabilized, the same backwards compatibility policy applies and the shape of the component should not change.

This restores the static properties that were unintentionally removed from the `__experimentalLinkControl` component that was moved to `DeprecatedExperimentalLinkControl`.

Fixes #62887.
