Feature: #89747 - Custom tables with record browser in forms

See Issue #89747

Description

The record browser in forms now accepts arbitrary custom tables if configured accordingly.

The option browsableType of the Inspector-Typo3WinBrowserEditor can be set to an arbitrary table:

TYPO3:
  CMS:
    Form:
      prototypes:
        standard:
          formElementsDefinition:
            MyCustomElement:
              formEditor:
                editors:
                  # ...
                  300:
                    identifier: myRecord
                    # ...
                    browsableType: tx_myext_mytable
                    propertyPath: properties.myRecordUid
                    # ...

Similar to the ContentElement form element custom logic must be added in the matching frontend partial to actually display something for the selected record.

Impact

Form definitions can be set up to allow editors the selection of arbitrary database records and then render them using custom logic.
