runtime(dosbatch): improve '::' comment highlighting

Browse Source 
Added a syntax region for command blocks so that the highlighting of
`::` comments in them can be controlled.  The `dosbatch_colons_comment`
variable now controls if all `::` comments in a code block are
highlighted as comments or errors.  A `::` comment at the end of a
command block is always highlighted as an error.

This re-enables the highlighting of `::` comments in `.bat` files as
requested in #13666, while allowing control of highlighting them in
command blocks requested in #11778 and first attempted in #11980.

fixes: #13666

is used by default. You may select the former with the following line: >
