feat(table): add customizable table page break handler

[lezram]

I build an extension functionality for table page breaks.
My use case was to add a row before the page break and one after the page break.
Detected that it is similar to an already existing #1205
Maybe this is useful for others too.

• add custom onPageBreak event handler for table page breaks
  • listen on pageChanged event and call custom handler
  • as per existing table page break (pageChanged) implementation
    • if dontBreakRows: true is set the event is only called once
    • if it's not set there will be an event for each cell
