Fix inlining closures from local variables and functions
Previously, closures were not properly wrapped in parentheses for the `inline_local_variable` and `inline_call` assists, leading to the usages being incorrectly called:
```rust
fn main() {
let $0f = || 2;
let _ = f();
}
```
Now produces:
```rust
fn main() {
let _ = (|| 2)();
}
```
Instead of:
```rust
fn main() {
let _ = || 2();
}
```
Closes #15639
