[two_dimensional_scrollables] Fix repaint boundary override in builder delegate (#4814)

Fixes https://github.com/flutter/flutter/issues/133582

This fixes a small bug where we accidentally overwrote the default of addRepaintBoundaries

Because of this, I had to refactor a test here that used keys to identify children, but now that an additional render object widget is inserted through the RepaintBoundary, the look-ups broke.
