[AutoDiff] Simplify conditions enabling differentiable programming. (#30765)
Previously, two conditions were necessary to enable differentiable programming: - Using the `-enable-experimental-differentiable-programming` frontend flag. - Importing the `_Differentiation` module. Importing the `_Differentiation` module is the true condition because it contains the required compiler-known `Differentiable` protocol. The frontend flag is redundant and cumbersome. Now, the frontend flag is removed. Importing `_Differentiation` is the only condition.
