This PR fixes a crash when an arbitrary value was malformed and crashed
the build.
If you have a utility like `[--btn-border:var(--color-maroon)/90)]`
which is malformed, it will crash the build. It might not be easy to
spot but the easy is the additional `)` after the `90`.
The reason this crashes is because we parse the value
`var(--color-maroon)/90)` and when we see `)` we assume it's the end of
a "function" which also assumes it was preceded by a `(`. This is not
the case and we crash.
This PR fixes that by not assuming the parsed object is available and
uses `?` to be safe and only access `nodes` if it's available.
I'm actually not 100% sure what the best solution is in this scenario
because these candidates could (and will) be returned from Oxide so even
if we throw a more descriptive error, it will still crash the build and
you might not even have control over the candidate.
This candidate will now eventually generate the following CSS:
```css
.\[--btn-border\:var\(--color-maroon\)\/90\)\] {
--btn-border: var(--color-maroon) / ;
}
```
Which still looks odd, but even Lightning CSS doesn't throw an error in
this case (because it's a CSS variable definition), so I think it's the
best we can do. If you open your devtools you will see the weird values,
so it's still debug-able.

Fixes: #17064
## Test plan
Manually tested the candidate that crashed it, and after the change
generated the above CSS. Then used it in JSFiddle to proof it's fixed
now. https://jsfiddle.net/z850ykew/
Couldn't use Tailwind Play because the candidate will cause a crash
there as well 😅
