[Quant][PT2E] Enable linear and linear-unary post-op quant recipe for x86 inductor quantizer (#106781)
**Summary**
Add linear and linear-unary post-op quantization recipe to x86 inductor quantizer. For PT2E with Inductor. With this, the quantization path will add `quant-dequant` pattern for linear and linear-unary post op.
**Test plan**
python test/test_quantization.py -k test_linear_with_quantizer_api
python test/test_quantization.py -k test_linear_unary_with_quantizer_api
