llama : reuse graph result instances across scheduler reserves (#32089)

Allocate gf_res_reserve and both gf_res_prev entries once in the llama_context constructor. Add llm_graph_result::set_max_nodes() and reset the existing instances in sched_reserve() instead of recreating them. get_gf_res_prev() now only selects the arena for the current batch.
