libcamera: class: Provide move and copy disablers
It can be difficult to correctly parse the syntax for copy/move and the
associated assignment operators.
Provide helpers as syntactic sugar to facilitate disabling either the
copy constructor, and copy assignment operator, and the move constructor
and move assignment operator in a way which is explicit and clear.
