Negative values throw `Unsupported expression: UnaryExpression`

### Describe the issue

Given code like this:

```tsx
...
scrollableContentContainer: {
display: "flex",
flexDirection: "column",
marginBlock: -4,
// ^^ This causes StyleX to throw
minBlockSize: 0,
position: "relative",
},
...
```

StyleX throws:

```

```
As a workaround I need to quote negative units like `"-4px"` in this case.

Thanks!

### Expected behavior

`-4` should work for properties that support number-based values such as length-based properties. For example, `inset-*`, `margin-*`, etc.
