Handle updating cluster metadata search attributes info when using SQL DB

[rodrigozhou]

What changed?
Register the pre-allocated custom search attributes when starting new instances of Temporal Server using SQL DB as visibility storage, or during the first start of the Server after upgrading to v1.20.

Why?
Support for advanced visibility using SQL DB: custom search attributes are pre-allocated and doing this automatically provides a more seamless experience to the user.

How did you test it?
Start new Server before changes, and then after. Logs show the search attributes being registered successfully:

{"level":"info","ts":"2023-01-27T17:16:01.894-0800","msg":"Successfully registered search attributes.","component":"metadata-initializer","cluster-name":"active","logging-call-at":"fx.go:733"}

Potential risks
No.

Is hotfix candidate?
No.
