Added kl_div frontend

[zaRizk7]

I was trying to add test cases and ran pytest on the test_loss_functions.py file, it seems when i try to run it certain functions in the helper like array_or_none does not exists which gave me an error while testing. I tried it on my other files for empirical testing and the results between original functionals for kl_div should work as expected.

closes #9183

Also, may I have this request linked to my issue? I can't seem to find the settings icon to link to it by myself. My issue is #9183

@juliagsy may I ask for my current code progress to be reviewed? If there's like any additional bug I could fix as currently, the test case for the current kl_div I have pushed have been successful as of right now.

Hey! Thanks for contributing! I'll review within the next 2 days! Meanwhile, could you please resolve the conflicts in the test file? Thanks!

Hey there! Great work so far! Some changes related to test failures are needed, please request my review once again when you're done, thanks!

[juliagsy]

Hey there! Thanks for the changes!

The tests for kl_div are still failing, you may check the workflow for the failures, or you may run the tests locally by executing:

python3 -m pytest ivy_tests/test_ivy/test_frontends/test_torch/test_loss_functions.py::test_torch_kl_div

You should ensure that the tests for kl_div are passing for all backends.
Thanks!

@juliagsy turns out the error I got is due to I forgot to add unsupported decorator for half precision. It should work fine now as it has passed all of the tests in my machine.
