PEL: Manager: Implemented the GetPELIdFromBMCLogId dbus method

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

Tested:
- Tested by below unit test cases.
 - With valid OpenBMC Event Log ID
 - With invalid OpenBMC Event Log ID

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