兼容版通用检查点
现已支持如下并行转换，局部限制：tp和wp暂不支持互转，且tp和wp必须为整数倍转换。
使用方式
本方案为通过运行时任务生成meta，利用离线脚本转换ckpt的方案，转换同时需要用到新旧配置的metadata.pt文件。可通过设置config中generate_meta_data来在运行任务时独立保存metadata.pt。对于此PR后续保存的ckpt将自动同时生成metadata.pt文件。
精度验证
验证使用dump的数据集来确保数据一致，未启用determinsitic会有略微误差。baseline为0-200 step训练，其他实验组从100 step使用转换的ckpt进行续训。
