tdf#71409: Pre-create sum/equal and ok/cancel buttons...

in the sc formula bar at the start instead of adding/
removing them to/from vcl ToolBox when required.
To maintain the functionality, do hide/show and
enable/disable the button pairs (sum/equal, ok/cancel)
during mode switch. This solves the excess a11y events
problem of tdf#71409 because this patch get rid of
the usages of vcl's Toolbox::Remove() and its accessibility
module dependencies which seems to be the root cause.
