Add optional textInputField parameter to FlottformTextInputHost for attaching text

[TamaraBogantseva]

Description

To improve flexibility, we can modify the FlottformTextInputHost to accept an additional, optional parameter named textInputField during initialization. This parameter will allow developers to specify an input field directly, to which text can be attached. If provided, textInputField will be used to handle text input; if not, the default behavior remains unchanged.
We already did this for createTextInput in default-component.
