Auto merge of #13406 - Mylainos:issue-13377, r=jdm

Extract panic-catching for JS engine callbacks into a separate function

All of our generated code for script contains inline code like this:
```
let result = panic::catch_unwind(AssertUnwindSafe(|| {
    ...
};
match result {
    Ok(result) => result,
    Err(error) => {
        store_panic_result(error);
        return false;
    }
}
```
This PR change it to something like this:
```
wrap_panic(|| { ... }, false)
```
