As title. Introduce fusion patterns to enable fusing quantized convolution and linear graph patterns into a custom op. ## Changes Introduce the concept of using custom pattern detection functions to detect graph patterns rather than solely relying on SubgraphMatcher. The issue with SubgraphMatcher is that a large number of graph patterns may need to be exported to obtain variants for different combinations of decompositions/quantization workflows. Having a custom detection function improves maintainability. Implement detection + replacement functions for quantized linear and quantized conv2d.
