Add system & primary clipboards as special registers

These special registers join and copy the values to the clipboards with
'*' corresponding to the system clipboard and '+' to the primary as
they are in Vim. This also uses the trick from PR6889 to save the values
in the register and re-use them without joining into one value when
pasting a value which was yanked and not changed.

These registers are not implemented in Kakoune but Kakoune also does
not have a built-in clipboard integration.
