QAccessible*Interface: disable copying

These are polymorphic classes, so they shouldn't be copied (which
invites slicing), so disable copy and move SMFs in the base classes
for implementations to inherit the safe default.

[ChangeLog][QtGui][Potentially Source-Incompatible Changes] The
QAccessible*Interface classes were made uncopyable. As polymorphic
types, they shouldn't be.

Found in API-review for QAccessibleViewportInterface, but applying to
all others, too, to avoid c'n'p propagation of missing
Q_DISABLE_COPY_MOVE going forward.
