PEL: private header in JSON

The PELTool application is able to convert sections to JSON. This commit
takes care of converting the private header section to JSON.

private header section in JSON sample:

"Private Header":[
 {"Section Version": "1"},
 {"Sub-section type": "0"},
 {"Log Committed by": "0x1000"},
 {"Entry Creation": "10/24/2019  15:50:08"},
 {"Entry Commit": "10/24/2019  15:50:08"},
 {"Creator ID": "BMC"},
 {"Creator Implementation": ""},
 {"Platform Log ID": "0x50000004"},
 {"Log Entry ID": "0x50000004"}
]
