@next/font return types (#42753)

Currently the return type is the same when you declare a variable and
when you don't.
```tsx
const inter1 = Inter()
const inter2 = Inter({ variable: "--inter-font" })

inter1.variable // string | undefined
inter2.variable // string | undefined
```

With this change you get a type error if you try to access `.variable`
without providing a variable name.
```tsx
const inter1 = Inter()
const inter2 = Inter({ variable: "--inter-font" })

inter1.variable // Property 'variable' does not exist on type 'NextFont'.ts(2339)
inter2.variable // string
```
