本PR修复了以下两个tensor切片索引bug：

1.修复Tensor索引赋值调用set_value op出现的显存泄露问题，该问题主要是由Inplace策略的使用不当导致，本PR中已完成修复。

2.修复使用多个None类型索引时结果维度异常的问题

[Dy2stat]Allow users to switch eval/train mode when using @to_static to decorate a function (#37383) (#37432)

本PR之前使用@to_static装饰一个单独的function时，对于生成的Program无法切换train/eval模式，只能运行在train模式下。这也就导致动转静后用户多次调用function显存会一直增长。
本PR之后，使用@to_static装饰一个单独的function时，可以通过function.train()或者function.eval()的方式来切换train/eval模式。
