android: camera_request: Turn struct into a class

The Camera3RequestDescriptor structure is growing into an object with member functions. Turn it into a class, uninline the destructor to reduce code size, explicitly disable copy as requests are not copyable, and delete the default constructor to force all instances to be fully constructed.
