Doc: Fix return type of QWeakPointer assignment operators

Imprementation of QWeakPointer assign operators have return types
that are references. However, in qsharedpointer.h where separate
declarations are held for documentation purposes, the reference
qualifiers were missing. This led to incorrect documentation being
generated.
