[renderers] Possibility to choose whether `onChange` is triggered at each typed character or on focus loss for text-based inputs

### Is your feature request related to a problem? Please describe.

Currently (at least with Material UI renderer and I think also with vanilla React renderer), the `onChange` method is called each time a character is typed in the text-based input (with eventual debounced introduced by the user).
For some use cases, it would be preferable to trigger the `onChange` method only when the concerned text-based input looses the focus. (regardless of eventual debounce)

Of course, both scenarii are valid, and it's really a matter of personal preference.

### Describe the solution you'd like

It would be nice to upgrade all text-based renderers to have the two possibilities:

- trigger `onChange` when a character is typed in the input.
- trigger `onChange` when the input looses focus and its content has actually changed.

Users should be able to choose between the two behaviors by configuring a simple option in the JsonForms configuration.

### Describe alternatives you've considered

As a user, it should already be possible to achieve this by providing custom renderers and overriding the behavior in each used text-based renderer. But it would be so much cleaner if the change was centralized and inherited by supporting renderers.
Plus, as this looks like a recurring user need, we should probably consider this evolution intead of having diverging user renderers.
