Add option for fields to define template

[piotrpog]

I think it could be useful if we could define template for the fields. Then we could run something like render() method on field value (inspired by render() on entry, introduced in craft 5):

{{entry.exampleField.reneder()

Within template, element (object that has the field), field (field instance) and value variables would be available. Any additional variables could be passes through optional render() method parameter.

Example usage:

• Ckeditor field template containing wrapper with tailwind prose class.
• Asset field template containing markup for lazyload or multiple breakpoints functionality.
• Verbb Hyper field template containing logic for rendering multiple links and some default classes for rendering links as buttons.
• Date field template containing proper formatting setting and <time> wrapper.
