    Execute an FX graph Node-by-Node and
    record the shape and type of the result
    into the corresponding node.

    Example:
         In this example, we record the shape
         and data type of a module given
         an example input ``torch.randn(50, D_in)``.
         We print the name, shape and dtype of each node.

        class TwoLayerNet(torch.nn.Module):
            def __init__(self, D_in, H, D_out):
                super().__init__()
                self.linear1 = torch.nn.Linear(D_in, H)
                self.linear2 = torch.nn.Linear(H, D_out)
            def forward(self, x):
                h_relu = self.linear1(x).clamp(min=0)
                y_pred = self.linear2(h_relu)
                return y_pred
        N, D_in, H, D_out = 64, 1000, 100, 10
        x = torch.randn(N, D_in)
        y = torch.randn(N, D_out)
        model = TwoLayerNet(D_in, H, D_out)
        gm = torch.fx.symbolic_trace(model)
        sample_input = torch.randn(50, D_in)
        ShapeProp(gm).propagate(sample_input)

        for node in gm.graph.nodes:
            print(node.name, node.meta['tensor_meta'].dtype,
                node.meta['tensor_meta'].shape)

        The output of this code is:

        x torch.float32 torch.Size([50, 1000])
        linear1 torch.float32 torch.Size([50, 100])
        clamp_1 torch.float32 torch.Size([50, 100])
        linear2 torch.float32 torch.Size([50, 10])
        output torch.float32 torch.Size([50, 10])

    Args:
         module (GraphModule): The module to be executed
         fake_mode (FakeTensorMode): A fake mode for copying the gm
