modify the check condition of Conv-> Add/Sub/Mul/Div folding
Relax the check condition of Conv-> Add/Sub/Mul/Div folding to accept that the input tensor of Add/Sub/Mul/Div is floating type or the promoteTypes of the input tensor of Add/Sub/Mul/Div is equal to the type of conv weight.
Relaxing this condition is mainly to deal with a common situation in models:
the conv output add/sub/mul/div an integer tensor or integer scalar tensor.
