Simplify invokeMethod implementations using QSlotObject helpers

Browse Source 
Remove duplication for overloads covering member function pointer
or function pointer cases, as those are now covered by the new
QtPrivate::makeSlotObject helper.

\since 5.10
\threadsafe
\overload
Invokes the \a function in the event loop of \a context using the connection type Qt::AutoConnection.
\a function can be a functor or a pointer to a member function. Returns \c true if the function could
be invoked. Returns \c false if there is no such member or the parameters did not match.
The return value of the function call is placed in \a ret.
If \a type is set, then the function is invoked using that connection type. Otherwise,
Qt::AutoConnection will be used.
