Feature: #79225 - Plugin preview with Fluid

Description

The page TSconfig to render a preview of a single content element in the Backend has been improved by allowing the rendering of plugins as well.

The following option allows to override the default output of a plugin via page TSconfig:

mod.web_layout.tt_content.preview.list.example = EXT:site_mysite/Resources/Private/Templates/Preview/ExamplePlugin.html

All properties of the tt_content record are available in the template directly. Any data of the flexform field pi_flexform is available with the property pi_flexform_transformed as an array.

Note

If a PHP hook already is set to render the element, it will take precedence over the Fluid-based preview.
