Zhengxu Chen e62189ad69 [jit] Better checking for overload function declarations. (#59956)
Summary:
Pull Request resolved: https://github.com/pytorch/pytorch/pull/59956

Issue #50175. Basically two things need to be checked and are lacking currently:
1. Overload declarations should always have a single `pass` statement as the body.
2. There should be always an implementation provided for decls which doesn't
   have the torch.jit._overload decorator. So in this case we need to check
   whether we are actually compiling a function body with decorator ahead.

Test Plan:
python test/test_jit.py TestScript.test_function_overloads
