Case 1) Basic case

BEFORE [CircleRelu] | | [CircleConst] [CircleConst] | | | ----—+-------------------— | [CirclePadV2] | [CircleMaxPool2D] |

AFTER [CircleRelu] | | [CircleConst] [CircleNode] [CircleConst] | | | | | ----—+----— ----------—+-----------—+ | | [CirclePad] [CirclePadV2] | [CircleMaxPool2D] |

Case 2) During conversion from a PyTorch model into a Circle model, it is common that some 'Reshaping op', e.g., CircleTranspose, are inserted in-between operations to swith NCHW into NHWC and vice versa. This pass also needs to handle such situation.

BEFORE [CircleRelu] | | [CircleConst] [CircleConst] | | | ----—+-------------------— | [CircleTranspose] | [CirclePadV2] | [CircleTranspose] | [CircleMaxPool2D] |

AFTER [CircleRelu] | | [CircleConst] [CircleNode] [CircleConst] | | | | | ----—+----— ----------—+-----------—+ | | [CircleTranspose] [CirclePadV2] | [CirclePad] | [CircleTranspose] | [CircleMaxPool2D] |

Implements logo::Pass.
