Fix rebinding an allocator to the same type should result in the original allocator

[hdnpth]

1. This patch https://lists.llvm.org/pipermail/libcxx-commits/2022-October/045949.html introduces static_assert with the additional requirement on allocator — rebinding an allocator to the same type should result in the original allocator.

On the upcoming libcxx update I have got the following error:

/home/hiddenpath/ydb/contrib/libs/cxxsupp/libcxx/include/vector:367:5: error: static assertion failed due to requirement 'is_same<NKikimr::NMiniKQL::TMKQLAllocator<NYql::NUdf::TUnboxedValue, NKikimr::NMiniKQL::EMemorySubPool::Temporary>, NKikimr::NMiniKQL::TMKQLAllocator<NYql::NUdf::TUnboxedValue, NKikimr::NMiniKQL::EMemorySubPool::Default>>::value': [allocator.requirements] states that rebinding an allocator to the same type should result in the original allocator

2. I have found some mistaken return keywords in various functions (since they have a void return type we have to get rid of them) as well.
