[quant][fx] Move rnn ops to backend_config_dict (#75316)
Summary:
Pull Request resolved: https://github.com/pytorch/pytorch/pull/75316
att, similar to previous PRs, this one moves dynamically quantized rnn ops
to backend_config_dict
Currently the dtype check is not yet enabled, so we provided the dtype_configs but it is not really used yet,
we will enable it a bit later after we moved everything to backend_config_dict
Test Plan:
python test/test_quantization.py TestQuantizeFx
python test/test_quantization.py TestQuantizeFxOps
python test/test_quantization.py TestFXNumericSuiteCoreAPIs
