tdf#140762 Set texts for items in "Borders" dropdown button

Associate textual descriptions with the images for the items
in the "Borders" dropdown button in Calc's formatting toolbar.

This e.g. makes them show up as tooltips when hovering over
the images with the mouse and makes them accessible to
screen readers (e.g. Orca with the gtk3 VCL plugin now says
those texts instead of just saying "item 1", "item 2",...).

This also adds the strings for the items where no corresponding
ones exist yet.
