Support interpolation in state strings

[Xiphe]

In order to support dynamic state declarations

Given I have a state property state="onChange:set(${stateGroup}Prename)"
When I transform the property
Then I expect the transformed option to be

state={[{ as: 'onChange', setter: 'set', key: `${stateGroup}Prename` }]}

Or better only when used like this:

state={`onChange:set(${stateGroup}Prename)`}
