[libcamera-devel] [PATCH v3] android: Camera3RequestDescriptor: Provide a constructor for StreamBuffer

Provide a constructor for StreamBuffer and use that while populating
Camera3RequestDescriptor::buffers_ vector. Also provide the default
move-constructor (required as StreamBuffer is stored in a vector in
Camera3RequestDescriptor) and destructor for the StreamBuffer struct.
Also declare a default move assignment operator and disable the
copy constructor and move operator explicitly with
LIBCAMERA_DISABLE_COPY().
While at it, initialize pointers members in the StreamBuffer struct
to nullptr, with StreamBuffer::status set to Status::Success by default.
