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)
```
