[Op] Support for repeat_interleave backward

[pmarkovicTT]

Problem

Test for Llama 3.2 model backward fails with NotImplementedError: repeat_interleave

Seems like there is missing backward implementation for the op in forge/forge/op/eval/forge/tm.py

Repro

Run pytest forge/test/mlir/llama/test_llama_backward.py with @pytest.mark.parametrize("model_path", ["meta-llama/Llama-3.2-1B"])
