c++: Rewrite members for all deduction guides. [PR96199]
After the last patch, it occurred to me that we could run into the
specialization issue with non-alias deduction guides as well, so this patch
extends the rewriting to C++17 mode.
Doing this revealed that we weren't properly pushing into class scope for
normalization.
