This method factors these schemas into the "core" functional signature which is equal across all versions. Here is what normalization happens to the schema to convert it to a signature: - The overload name is stripped (name is retained, since it expresses semantic content about what the function does) - Inplace is set False - Out arguments are stripped - Mutable post_self_positional args are converted to returns - Mutability annotations are stripped (this is sound because you cannot overload on mutability annotation) - Return names are stripped since they are not overloadable and some variants have return names but some not - TensorOptions are dropped because out= variants of factory functions don't include them (and we want to be able to pair up factory functions with their out variants) Finally, we want to be able to pair up related "view" and their corresponding "view_copy" operators. We do this by optionally stripping the trailing "_copy" from the base name.
