[quant][pt2e] Refactor conv related annotation for XNNPACKQuantizer (#110308)
Summary:
Since we changed IR that we are working with to pre autograd aten IR, it's easier
to use plain pattern match instead of relying on source_matcher_utils now, this
PR refactors the annotation for conv to use aten ops directly.
Also fixed reentrant test after this change.
Test Plan:
python test/test_quantization.py TestQuantizePT2E
