[reland][quant] Remove nn.quantized.ReLU module and nn.quantized.functional.relu (#47415) (#48038)
Summary:
Pull Request resolved: https://github.com/pytorch/pytorch/pull/48038
nn.ReLU works for both float and quantized input, we don't want to define an nn.quantized.ReLU
that does the same thing as nn.ReLU, similarly for nn.quantized.functional.relu
this also removes the numerical inconsistency for models quantizes nn.ReLU independently in qat mode
