[quant][embedding qat] Support non-partial functions in qconfig comparison (#68067)
Summary:
Pull Request resolved: https://github.com/pytorch/pytorch/pull/68067
Embedding QAT uses a NoopObserver class for activation,
and a FakeQuant for weight, make sure that qconfig comparison
functions properly for a mix of partial function and class in
qconfig.
Test Plan:
`pytest test/quantization/eager/test_quantize_eager_qat.py -v -k "test_embedding_qat_qconfig_equal"`
