b9341c8713 [AutoDiff] Fix protocol witness SILGen for @differentiable class methods. (#32639)
During protocol witness SILGen for `@differentiable` class methods,
replace the `AutoDiffDerivativeFunctionIdentifier` generic signature
with the witness thunk substitution map's generic signature.

Resolves TF-1180: vtable SIL verification error.
