[autoparallel] bypass MetaInfo when unavailable and modify BCAST_FUNC_OP metainfo (#2293)

* [autoparallel] align the data_ptr with the old version of auto activation checkpoint pipeline

* [autoparallel] using fwd_time and bwd_time instead of fwd_flop and bwd_flop

* [autoparallel] specifycomm nodes' memory cost in construct chain

* [autoparallel] fix wrong runtime apply calculation

* [autoparallel] fix wrong runtime apply calculation

* [autoparallel] fix wrong runtime apply calculation

* [autoparallel] bypass metainfo when available and modify BCAST_FUNC_OP
