Add config completion.addSemicolonToJumps

Example
---
```rust
fn f() -> i32 {
    if true {
        $0
    }
}
```

**addSemicolonToJumps: true (default)**

```rust
fn f() -> i32 {
    if true {
        return $0;
    }
}
```

**addSemicolonToJumps: false**

```rust
fn f() -> i32 {
    if true {
        return $0
    }
}
```
