add zoom-* utilities (#20020)

This PR adds new `zoom-*` utilities.

The `zoom-*` utilities accept bare values that are transformed into `%`
based values, and arbitrary values:

| Class | CSS |
| -- | -- |
| `zoom-50` | `zoom: 50%;` |
| `zoom-[1.1]` | `zoom: 1.1;` |
| `zoom-(--value)` | `zoom: var(--value);` |


This also adds the `zoom` property after the `transform` related
properties. Initially I added it right after `scale`, because logically
they are close together. But then `zoom-*` would sit between `scale` and
other tranfsorm related properties which is a bit weird. Instead, I
moved it after `transform`.

## Test plan

1. Added new zoom based tests
2. All other tests still pass
