Spreadsheet: add status bar

This implements the status bar as footer region in the
spreadsheet editor.

It shows the total number of rows and columns as well
as how many rows are actually visible (based on the filter).

The implementation stores the stats in a runtime struct during
drawing and the status bar reads from that struct.

Ref T86142.
