Marc Mutz 1219dbcd12 QPointer: ensure construction from nullptr is constinit'able 
Construction from nullptr wasn't, before, because it was using the
QPointer(T*) constructor, which cannot be constexpr. Add a constexpr
QPointer(std::nullptr_t) constructor to enable this use-case.

This requires to mark the (T*) constructor as Q_WEAK_OVERLOAD,
otherwise legacy construction from a literal 0 would be ambiguous.

No documentation changes needed, as the set of valid expressions
(apart from constinit'ing) has not changed. Mention the nullptr ctor,
though, without \since.

Add a test to confirm that contruction from derived still works.
