[srp-server] log the content of processed SRP update message (#8131)

Browse Source 
This commit updates the `Srp::Server` to log the processed info in a
received SRP Update message, such as host name, lease times, host
addresses, all services (and sub-types) being added or removed. The
info is logged before invoking the "update handler" and/or committing
the info into existing data. This change can help with debugging
issues.
