Add attrProto.release_s interface (#22977)

### Description
Add AttributeProto.release_s interface, which is used to obtain the
string in the attribute using move semantics instead of copying it



### Motivation and Context
The ep_context node stores a lot of information in attributes, which may
cause the memory usage to increase. Use this interface to avoid memory
waste
