Chuanqi Xu 5937d7f907 [C++20] [Modules] Correct the behavior for adding mangling for lambda in modules ...

The common pattern of the problem is the lambda is somehow leaked from a
non-inline non-internal function in module purview, and we need to
define a mangling for it by the discuss from
https://github.com/itanium-cxx-abi/cxx-abi/issues/186

The root cause of the issue is a mismatch that give up too quickly when
ManglingContextDecl is nullptr. But we can still get the context
information from DC.
