topology2: pipeline: add constraints on pipeline.priority attribute

Add constraints on valid pipeline priority values and document the semantics so that 0 is considered the highest priority and such pipeline should be run first. The range matches definitions in include/ipc4/pipeline.h and SOF_IPC4_MAX_PIPELINE_PRIORITY. Signed-off-by: Kai Vehmanen <[email protected]>
