redfish-spdm-attestation: Update the D-bus object path

Change D-Bus object paths from PascalCase to snake_case for consistency:
- /xyz/openbmc_project/ComponentIntegrity/{ComponentIntegrityId} →
 /xyz/openbmc_project/component_integrity/{component_integrity_id}

- /xyz/openbmc_project/TrustedComponents/{TrustedComponentId} →
 /xyz/openbmc_project/trusted_components/{trusted_component_id}

- /xyz/openbmc_project/certs/devices/{ChassisId}/{CertId} →
 /xyz/openbmc_project/certs/devices/{chassis_id}/{cert_id}

 On the D-Bus Daemon side, we propose that the dbus objects are organized in the
 following way:
 
-- `/xyz/openbmc_project/ComponentIntegrity/{ComponentIntegrityId}`
-- `/xyz/openbmc_project/TrustedComponents/{TrustedComponentId}`
-- `/xyz/openbmc_project/certs/devices/{ChassisId}/{CertId}`

 In BMCWeb, we can reconstruct the following redfish URI by querying the
 associated Chassis from the trusted component:
