runtime(dosbatch): Add syn-sync to syntax file
Closing parentheses were often highlighted as errors.
Add a syntax sync command to reduce the error.
Also fix that `defined` was not highlighted as an operator inside
parentheses. E.g.:
```
if defined foo (
if defined bar (
...
)
)
```
The first `defined` was highlighted but the second one was not.
