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

Browse Source 
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.
