Resolves#14772.
This PR fixes an issue where utilities like `ps-2` were sorted earlier
in the generated CSS than `px-3`, causing `ps-2` to not override `px-3`
as expected.
This happened because `px-3` uses `padding-left` and `padding-right`,
and `ps-2` uses `padding-inline-start`, and in `property-order.ts` we
sort those properties as follows:
```js
...
'padding',
'padding-inline',
'padding-block',
'padding-inline-start',
'padding-inline-end',
'padding-top',
'padding-right',
'padding-bottom',
'padding-left',
...
```
Since `padding-left` and `padding-right` both appear later than
`padding-inline-start`, the `px-3` utility is sorted later in the CSS
since all of its properties are later in the sort order than all of
properties in `ps-2`.
To fix this, I'm using our internal `--tw-sort` property to tell
Tailwind to sort the `px-3` utility as if it used `padding-inline` to
ensure that it's sorted earlier in the CSS.
This PR applies this same fix for the `padding` utilities,
`scroll-margin` utilities, and `scroll-padding` utilities. No changes
have been made to the `margin` utilities because we were already
handling this correctly there.
Here you can see that `pl-2` overrides `px-6` as you'd expect:
<img width="1041" alt="image"

…and now with the change in this PR, `ps-2` also overrides `px-6` as
you'd expect:
<img width="1043" alt="image"
src="https://github.com/user-attachments/assets/c6799416-9c80-4fd5-bce4-ea1e4da53968">
