semantic: incorrect semantic check for has same name LabeledStatement nested in LabeledStatement

[Dunqing]

Reproduction:

This bug was found in https://github.com/oxc-project/monitor-oxc/actions/runs/10482911458/job/29034791059

Minimal reproduction

oxc playground

TOP: {
  L: console.log(1);
  L: console.log(2);
};

The above code reports the following errors in the playground

❗ Identifier `L` has already been declared
❗ Identifier `L` has already been declared

Expected result

There are no semantic errors. I've run the code in Chrome devtools and that works well

We first need to change the diagnostic here

oxc/crates/oxc_semantic/src/checker/javascript.rs

Line 647 in a4247e9

ctx.error(redeclaration(labeled.name, *span, labeled.span));

And then figure out what's wrong in the label builder https://github.com/oxc-project/oxc/blob/main/crates/oxc_semantic/src/label.rs
