PEL: Add hidden and subsystem properties

This story adds a new PELEntry interface
org.open_power.Logging.PEL.Entry on existing PEL entry. Then we add 2
properties with their values initialized during the creation of the Interface.

Tested:
1. Verified that the new PEL creation with recoverable error sets the new
attribute in the PEL.entry Interface.
2. Restarted the phosphor-log-manager daemon and made sure the flag is set
with the new Interface created for d-bus
3. Tested with passing a RAWPEL to create from file system and verified
that the hidden attribute is set accordingly on the PEL.entry Interface.
4. Copied the new format error to a system with old code and restored
the error log to make sure it does not crash.
5. Validated both hidden and subsystem properties.
