PEL: Manager: Implemented the GetBMCLogIdFromPELId dbus method

In OpenPOWER based system, the application may need to get
the OpenBMC event log id by using the PEL id (aka Entry ID (EID) which
is a unique id in the PEL) so added the interface for the same.

Tested:
- Tested by below unit test cases.
 - With valid PEL ID
 - With invalid PEL ID

- Tested by using busctl command
 - With valid PEL ID
```
   busctl call xyz.openbmc_project.Logging \
   /xyz/openbmc_project/logging org.open_power.Logging.PEL \
   GetBMCLogIdFromPELId u 1342211909
   >>> u 4534
```
 - With invalid PEL ID
```
   busctl call xyz.openbmc_project.Logging \
   /xyz/openbmc_project/logging org.open_power.Logging.PEL \
   GetBMCLogIdFromPELId u 0xFFFFFFFF
   >>> Call failed: Invalid argument was given.
```
