Function try_differentiate

    view: &ResolvedView<Op>,
    outputs: &[GlobalValKey<Op>],
    wrt: &[Op::InputKey],
    pass: DiffPassId,

Fallible form of differentiate.

This returns [chainrules::ADRuleError] when a primitive cannot emit a JVP rule, allowing downstream frontends to surface missing extension rules as normal errors instead of panics.
