tdf#120047 Support attribute harpoon/wideharpoon in Math

... for an alternative style of vectors.

They are vec/widevec analogs but with COMBINING RIGHT HARPOON ABOVE
(U+20D1).  The new attribute names are deliberately long in order to
make fewer accidental collisions with variable names in formulae of
exising documents.

This also adds a glyph uni20D1 to OpenSymbol.
