registries: make registration dynamic

Rather than having to manually hook code for registries, add a small
registration function to the registry header and use this registration
results throughout the registry interactions.

Tested:

Confirmed registries have same behavior.

```
$ curl -s -k https://localhost:18080/redfish/v1/Registries/ | jq '.Members | map(."@odata.id")'
[
  "/redfish/v1/Registries/Base",
  "/redfish/v1/Registries/HeartbeatEvent",
  "/redfish/v1/Registries/OpenBMC",
  "/redfish/v1/Registries/ResourceEvent",
  "/redfish/v1/Registries/TaskEvent",
  "/redfish/v1/Registries/Telemetry"
]
```

```
$ curl -s -k https://localhost:18080/redfish/v1/Registries/TaskEvent/TaskEvent | jq ".Messages | keys"
[
  "TaskAborted",
  "TaskCancelled",
  "TaskCompletedOK",
  "TaskCompletedWarning",
  "TaskPaused",
  "TaskProgressChanged",
  "TaskRemoved",
  "TaskResumed",
  "TaskStarted"
]
```
