add cache for api object_info

### Feature Idea

if my installation of comfy have lot of customs nodes, then the api will cost tens of seconds, sometime cost minutes, to load. So may be add a short time cache for this api is need.
@routes.get("/object_info")
async def get_object_info(request):
with folder_paths.cache_helper:
out = {}
for x in nodes.NODE_CLASS_MAPPINGS:
try:
out[x] = node_info(x)
except Exception as e:
logging.error(f"[ERROR] An error occurred while retrieving information for the '{x}' node.")
logging.error(traceback.format_exc())
return web.json_response(out)
