OPENTHREAD_CONFIG_SRP_SERVER_SERVICE_UPDATE_TIMEOUT macro

@def OPENTHREAD_CONFIG_SRP_SERVER_SERVICE_UPDATE_TIMEOUT Specifies the timeout value (in milliseconds) for the service update handler. The default timeout value is the sum of the maximum total mDNS probing delays and a loose IPC timeout of 250ms. It is recommended that this configuration should not use a value smaller than the default value here, if an Advertising Proxy is used to handle the service update events.
