[ASAN] Fix Indirect Mem Leaks in Orchagent (sonic-net#2869)
Browse files Browse the repository at this point in the history 
**What I did**

Fix the Mem Leak by moving the raw pointers in type_maps to use smart pointers

**Why I did it**

```
Indirect leak of 83776 byte(s) in 476 object(s) allocated from:
