libcamera: buffer: Create a MappedBuffer
Provide a MappedFrameBuffer helper class which will map all of the Planes within a FrameBuffer and provide CPU addressable pointers for those planes. The MappedFrameBuffer implements the interface of the MappedBuffer allowing other buffer types to be constructed of the same form, with a common interface and cleanup. This allows MappedBuffer instances to be created from Camera3Buffer types. Mappings are removed upon destruction.
