Feature: #47006 - Extend the widget identifier with custom string

See Issue #47006

Description

The parameter customWidgetId has been introduced for fluid widgets. This string is used in the widget identifier in addition to the nextWidgetNumber .

The widget identifier is used to create the GET parameter names.

A good value for the customWidgetId is the {contentObjectData.uid} to ensure no collisions happen.

Example: .. code-block:: html

<f:widget.paginate customWidgetId=”{contentObjectData.uid}” …></f:widget.paginate>

Impact

Allows to use the same fluid widget more than once on one page in different content elements.
