libcamera: pipeline: Move camera data classes to the top level scope

Move the pipeline handler camera data classes, defined in the scope of
the respective pipeline handler class, to the top level of the libcamera
namespace. This prepares for the introduction of other classes that will
make use of them in the IPU3 and RkISP1 pipeline handlers. The UVC and
VIMC pipeline handlers are updated as well for consistency.
