[TASK] FormEngine: Inline BackendUtility::getRecordTitle as data provider

Provide the foundation to get rid of BackendUtility::getRecordTitle()
in FormEngine scope by:

 * adding a recordTitle field to the FormDataCompiler result array
 * adding a provider that fills in the recordTitle field
 * using the recordTitle in OuterWrapContainer where appropriate
 * ensuring the TcaTypesRemoveUnusedColumns provider does not remove
   columns used to generate the label.
