libcamera: pipeline: rkisp1: Breakout basic path handling to own class
The self and main paths are very similar and the introduction of support
for two simultaneous streams have made it clear their handling could be
abstracted in a separate class.
This is the first step to create such a class by breaking out the
initialization and storage of the video and subdevices. There is no
functional change in this patch.
