DSLX formatter does not provide a way to precisely comment on an else condition

[mikex-oss]

Describe the bug
The formatter either removes the comment or moves it inside the branch, which can be misleading.

To Reproduce
Steps to reproduce the behavior:

fn foo(x: u1) -> u32 {
    if x {
        u32:42
    } else {  // we take the else branch because
        u32:0
    }
}

is formatted to

fn foo(x: u1) -> u32 {
    if x {
        u32:42
    } else {
        // we take the else branch because
        u32:0
    }
}

That can be misleading as the comment is indented to match the return value here. As an attempted workaround,

fn foo(x: u1) -> u32 {
    if x {
        u32:42
    } 
    // we take the else branch because
    else {  
        u32:0
    }
}

is formatted to:

fn foo(x: u1) -> u32 {
    if x { u32:42 } else { u32:0 }
}

Expected behavior
Preserve the comment
