Simplify CSS when using utilities that use a *-0 or *-1 value (#20196)
## Why?


While inspecting a Tailwind-powered site, I noticed selectors like

```css
.inset-0{inset:calc(var(--spacing) * 0)}
.inset-x-0{inset-inline:calc(var(--spacing) * 0)}
.top-0{top:calc(var(--spacing) * 0)}
```

which seem a bit silly, not to mention more complex for the end-user
device parsing the CSS.

## Summary

This PR adjusts helpers to not generate `calc(... * 0)` expressions.

https://github.com/tailwindlabs/tailwindcss/pull/19095 does a similar
thing on CSS AST, but that doesn't run during the build proper.

## Test plan

Ran `pnpm build && pnpm test && pnpm test:integration`. (Some unrelated
tests failed on my machine, hopefully less in CI.)
