[MTIA Runtime] Add foreach_div ops to native_functions.yaml (pytorch#162732)

Summary: Quick fix for runtime support on foreach_div, see D81274963. Fixed an issue that I created in that diff so that the CIs pass.

Test Plan:
CIs created in D81274963 and D81286593 pass.

Added some logs in [aten_mtia_ops.py](https://www.internalfb.com/code/fbsource/[c56272ba042c43c65517dcac254364cf732fcfa9]/fbcode/mtia/host_runtime/torch_mtia/aten_mtia_ops.cpp?lines=3676) to all the foreach_div ops. We can see that the correct MTIA kernels are being invoked in the tests.
