accounts/abi: generate TryPack* methods for abigen v2 bindings (#31692)
1. Fix the error return format.
**todo**: ~~`bindtype` needs more complex logic to fix it.~~
`
if err != nil {
  return nil, err
}
if err == nil {
  return obj, nil
}
`
2. ~~Return pointer type object to avoid copying the whole struct
content.~~
3. Give the panic decision to the user.
4. Fix empty line at the end of function.

**TODO**: ~~fix some related test cases.~~
