[Quant][PT2E] Re-enable test case of conv add/add_relu recipe for x86inductorquantizer (#105638)
**Summary**
Re-enable the test case of `test_conv2d_binary_with_quantizer_api` and `test_conv2d_binary_unary_with_quantizer_api` for X86InductorQuantizer. We disable these 2 testcases previously due to the time out issue in internal CI.
**Test Plan**
```
python -m pytest test_x86inductor_quantizer.py -k test_conv2d_binary_with_quantizer_api
python -m pytest test_x86inductor_quantizer.py -k test_conv2d_binary_unary_with_quantizer_api
```
