tdf#122280: Hide Block selection mode from Calc

Currently, the Block Selection Mode in pop-up menu is dysfunctional
 in Calc. It is unreachable - when the user tries to choose "Block
 selection" from the pop-up menu that lies in the status bar, it
 shifts back to "Standard selection".
Hide the Block Selection mode from Calc, simply because it is
 dysfunctional and useless.
