0d176bef - [quant][improvement] Added quantized fill test for per channel quantized tensors

[quant][improvement] Added quantized fill test for per channel quantized tensors Summary: Previously, the quantization test suite only tested the fill operator for per tensor quantized tensors. This PR adds a test case for per channel quantized tensors. The existing `test_qtensor_fill`, which the newly introduced test function `test_qtensor_fill_per_channel` is based on, case had some ambiguous naming conventions. This PR renames some of those variables to be clearer. Test Plan: ``` python test/test_quantization.py test_qtensor_fill_per_channel ``` Pull Request resolved: https://github.com/pytorch/pytorch/pull/78661 Approved by: https://github.com/jerryzh168
