Defer construction of TextEdit/TextInput delegates.
Don't create instances of the delegate components until the item
gains focus, or the cursorVisible property is set to true.
Cursor delegates are typically small and relatively fast to create and
so won't have a significant cost during a one off focus in event,
but that cost can still add up when creating a number of TextInputs
or TextEdits at once. If a delegate that is instantiated immeditately
is required it is possible to instead create a child item and bind to
the cursorRectangle and cursorVisible properties.
