libcamera: camera: Move Camera::Private to header file

The Camera::Private class is defined in camera.cpp. To prepare for
allowing it to be subclassed by pipeline handlers, move it to a new
internal/camera.h header.

The \file comment block in camera.cpp now needs to explicitly tell which
camera.h file it refers to.
