[PDK-10107] OSAL: TimerP: Add new APIs to get timer reload count and current count

- Added New APIs:-
  - TimerP_getReloadCount: Get timer reload count
  - TimerP_getCount: Get timer current count

- Added implementation for DMTimer and RTI Timer (v1/v2)
- Not implemented for timer64(v0) - K2 devices
