Added OemComputerSystems and properties for provisioning

 - Added OemComputerSystems Schema for provisioning properties
 - Added "ProvisioningStatus" Oem property with EnumType
    1) NotProvisioned
    2) ProvisionedButNotLocked
    3) ProvisionedAndLocked

Intel secures platform firmware components using Intel PFR mechanism.
This may differ for other Oem's(non-intel platforms) but the properties
like Provisioned, Locked states should be of generic as per NIST SP
800-193. Added build time flag to enable/disable PFR supported platforms.

Tested:
 - By default provisioning feature is OFF, using GET method on below URI
verified Oem Property and observed no such property. This is default
behaviour on upstream.

URI: /redfish/v1/Systems/system
Response: No "Oem" property.

 - Enabled provisioning feature in Intel platforms and Verified using Systems
URI. Ran the redfish validator tool and no new issues found due to this
change.
URI: /redfish/v1/Systems/system
RESPONSE:
.....

"Oem": {
        "OpenBmc": {
            "FirmwareProvisioning": {
                "ProvisioningStatus": "NotProvisioned"
            }
        }
    }
