Always add layer(…) as the first param to @import (#15102)
This PR ensures that when we inject `layer(…)` into an `@import` that it
always gets inserted as the first param. The `layer(…)` has to come
first by spec.

Input:
```css
@import "./foo" supports(--foo);
```

Before:
```css
@import "./foo" supports(--foo) layer(utilities);
```

After:
```css
@import "./foo" layer(utilities) supports(--foo);
```
