[quant][graphmode][fx] Add reference option support for linear_dynamic_fp16 (#52534)
Summary:
Pull Request resolved: https://github.com/pytorch/pytorch/pull/52534
Currently linear_dynamic_fp16 has a signature that's tied to fbgemm/qnnpack
We'll need to produce a pattern equivalent to linear_dynamic_fp16 to support extensions
to other backends
Test Plan:
python test/test_quantization.py TestQuantizeFxOps.test_linear_dynamic_fp16
