BIOS: Implement HelpText and DisplayName properties

Introduce HelpText and DisplayName fields in the PLDM BIOS JSONs, these should
be parsed and passed to the D-Bus APIs that populates the BIOS table.
https://github.com/openbmc/phosphor-dbus-interfaces/blob/master/xyz/openbmc_project/BIOSConfig/Manager.interface.yaml#L68
Also, they have the same names in the Redfish schema.
https://redfish.dmtf.org/schemas/v1/AttributeRegistry.v1_3_3.json

Tested: test with JSON
