[Quant][fx] Remove WEIGHT_INDEX_DICT and BIAS_INDEX_DICT (#83263)
Summary:
This change adds in input_type_to_index mappings to the backend patterns for `nn.functional.linear`, `nn.functional.conv1d`, `nn.functional.conv1d`, and `nn.functional.conv3d`.
This let's us remove `WEIGHT_INDEX_DICT` and `BIAS_INDEX_DICT` from `prepare.py`.
Instead we pass around `backend_config` and check wether an arg is weight/bias agains that config
Test Plan:
```
python test/test_quantization.py TestQuantizeFx
python test/test_quantization.py TestQuantizeFxOps
```
