vim-patch:2a6be83: runtime(vim): Update base-syntax, improve :set backslash handling

Improve backslash handling in :set option values. There is no special
handling for options supporting Windows path separators yet.

See :help option-backslash.

Remove the vimSetString syntax group. Option string values cannot be
specified with a quoted string, this is a command terminating tail
comment.

fixes: vim/vim#16913
closes: vim/vim#17034
