Optimization for ConvNd if dropout=0.

As discussed in #2153

Thanks for adding this DoRA optimization to conv layers. Generally, this looks good, but I have one comment about the bias term.

Wondering: Do we not need to account for the possibility that the base layer has a bias term, same as we do for linear?

	if base_result is not None:
	bias = base_layer.bias
	if bias is not None:
	base_result = base_result - bias
