Long live Q_DISABLE_COPY_MOVE!
When using Q_DISABLE_COPY, clang-tidy reports:
warning: class 'Foo' defines a non-default destructor, a copy constructor
and a copy assignment operator but does not define a move constructor or a
move assignment operator [cppcoreguidelines-special-member-functions]
Add convenience macros to suppress move constructor/assignment
as well.
[ChangeLog][QtCore] Added macros Q_DISABLE_MOVE and Q_DISABLE_COPY_MOVE
complementing Q_DISABLE_COPY.
