- Introduce ggml_cann_graph_lru_cache to store multiple ggml_cann_graph objects. - Graphs are loaded on demand and evicted using LRU policy when capacity is exceeded. - Updated push, move_to_front, and clear methods to manage cached graphs efficiently. - Ensures reuse of graphs, reducing graph reconstruction overhead in CANN backend.
