Improve upgrade tool to pretty print --spacing(2) (#15596)
This PR improves the upgrade tool to make sure that newly upgraded
`--spacing(2)` CSS functions is pretty printed to prevent unambiguous
looking classes (even though it compiles correctly).

If you have a class such as `m-[calc(100dvh-theme(spacing.2))]`, then we
used to convert it to `m-[calc(100dvh-calc(var(--spacing)*2))]`. But
recently we introduced the `--spacing(2)` CSS function which means that
the output now looks like this instead: `m-[calc(100dvh---spacing(2))]`.

The triple `-` is valid because the first `-` is the minus sign, the
next two `-` characters are from the function.

One solution is to introduce spaces via underscores:

```
m-[calc(100dvh_-_--spacing(2))]
```

But a simpler solution, is to wrap the `--spacing(2)` in parens to
remove the underscores and improve the readability of the `---`
characters.

```
m-[calc(100dvh-(--spacing(2)))]
```
