libcamera: framebuffer: Add a function to check if planes are contiguous
Multi-planar frame buffers can store their planes contiguously in memory, or split them in discontiguous memory areas. Add a private function to check in which of these two categories the frame buffer belongs. This will be used to correctly handle the differences between the V4L2 single and multi planar APIs.
