Print space after formal generic params in fn type
Follow-up to #92238 fixing one of the FIXMEs.
```rust
macro_rules! repro {
($ty:ty) => {
stringify!($ty)
};
}
fn main() {
println!("{}", repro!(for<'a> fn(&'a u8)));
}
```
Before: `for<'a>fn(&'a u8)`
After: `for<'a> fn(&'a u8)`
The pretty printer's `print_formal_generic_params` already prints formal generic params correctly with a space, we just need to call it when printing BareFn types instead of reimplementing the printing incorrectly without a space.
