[202305]Change orchagent pop batch size from 8192 to 1024 (#16127)

Browse Source 
### Why I did it
Background running lua script may cause redis-server quite busy if batch size is 8192.
If handling time exceeded default 5s, the redis-server will not response to other process and will cause syncd crash.

```
