QAbstractFileEngine: Remove useless method overrides

Remove useless overrides of QAbstractFileEngine methods from the derived
classes. Also remove "This virtual function must be reimplemented by
all subclasses" passages from the QAbstractFileEngine's documentation.
There are pure virtual methods for such use cases. QAbstractFileEngine
already contains useful defaults for classes not supporting all the
functionality.
