2b6a0427 - [quant][core][feature] Implemented masked_fill for QuantizedCPU tensors

[quant][core][feature] Implemented masked_fill for QuantizedCPU tensors Summary: Previously, there was no suport for masked_fill for quantized tensors. This PR introduces the feature for quantized CPU tensors. A corresponding test case was added to test the impl. Most of the implementation is copied over from the fp kernel and adapted for quantized tensors. TODO: implement masked_fill for QuantizedCUDA tensors. Test Plan: ``` python test/test_quantization.py -k test_qtensor_masked_fill ``` Pull Request resolved: https://github.com/pytorch/pytorch/pull/78368 Approved by: https://github.com/vkuzo
