Description

Similar to lifetime elision hints, we should have label hints for control flow constructs.

That is for,

loop {
    loop: {
        break;
    }
    continue;
}

we should have the following hints

'0: loop {
    '1: loop {
        break '1;
    }
    continue '0;
}

For configs, enabled, disabled and a third option for only showing it in nested loop contexts would make sense I think

Research direction

Start by tracing the existing lifetime elision inlay hints and how their configuration is exposed. Define label hints for loop and control-flow constructs, including nested-loop filtering, and verify that the displayed labels match the example and the selected configuration mode.
