Adjust names of negated style methods (#11453)

This PR adjusts the names of the negated style methods by moving the
`neg_` to after the property name instead of before.

This will help keep related style methods grouped together in
completions.

It also makes it a bit clearer that the negation applies to the value.

### Before

```rs
div()
    .neg_mx_1()
    .neg_mt_2()
```

### After

```rs
div()
    .mx_neg_1()
    .mt_neg_2()
```
