QVariant: Support emplace
[ChangeLog][QtCore][QVariant] Implemented in-place construction for
QVariant. The constructor taking std::in_place_type<Type> constructs
an object of type Type directly inside QVariant's storage, without any
further copy or move operations. QVariant::emplace() does the same
when replacing the content of an existing QVariant and tries to reuse
previously-allocated memory.
Fixes: QTBUG-112187
