Description

A.修复动态图自动并行下，split_batches_for_accumulation与动手无法对齐的情况。如图

B.修复动态图自动并行下，enable_delay_scale_loss逻辑错误的问题。自动并行默认实现enable_delay_scale_loss，预期行为为：

1. 每个micro batch计算出loss
2. 反向传播
3. 对mini batch内的loss进行求和
4. 对loss进行scale，除以acc数

但当前动态图自动并行的行为为：

1. 每个micro batch计算出loss
2. 对该loss进行scale，除以acc数
3. 反向传播
4. 对mini batch内的loss进行求和

此外，由于enable_delay_scale_loss逻辑不完善，为自动并行增加开关

C. 修复静态图自动并行下，loss打印展示问题。loss预期的展示行为为：

1. 对每个micro batch的loss求和
2. 对求和结果进行scale，除以acc数

但当前静态图自动并行loss对打印展示行为为：

1. 对每个micro batch的loss进行scale，除以acc数
2. 进行求和

D. 修复函数名称错误，将traning修正为training
