Allow to edit or clear a TOSCA function value

In the properties assignment view, when a property that has a TOSCA
function value is selected, a button "Clear Value" will show allowing
to clear the property value.
This behaviour was changed to show the TOSCA function button, which,
when clicked, will open the TOSCA function modal with the function
values loaded, allowing to edit or clear the existing value.
