libcamera: v4l2_videodevice: Add V4L2BufferCache to deal with index mapping
In preparation for the FrameBuffer interface add a class that will deal with keeping the cache between dmabuf file descriptors and V4L2 video device buffer indexes. This initial implementation ensures that no hot association is lost while its eviction strategy could be improved in the future.
