Fix T59478: Information Bar Missing Data when in Sculpt Mode

Display statistics from CCG structure.

This makes values to be different from what is shown in object
mode, since CCG is operating on individual grids, and object
mode will stitch those grids. But on another, those values from
CCG is what sculpt mode is actually "sees" or "uses".

The number of faces should be the same in both sculpt and object
modes.
