Rollup merge of #62984 - nathanwhit:extra_semi_lint, r=varkor 
Add lint for excess trailing semicolons

Closes #60876.
A caveat (not necessarily a negative, but something to consider) with this implementation is that excess semicolons after return/continue/break now also cause an 'unreachable statement' warning.

For the following example:
```
fn main() {
    extra_semis();
}
fn extra_semis() -> i32 {
    let mut sum = 0;;;
    for i in 0..10 {
        if i == 5 {
            continue;;
        } else if i == 9 {
            break;;
        } else {
            sum += i;;
        }
    }
    return sum;;
}
```
The output is:
```
