Instead of calling `google::InitGoogleLogging()` directly, introduce an indirection via a new utility library. After this change, Sandboxed API should consistently use `sapi::InitLogging()` everywhere. For now, `sapi::InitLogging()` simply calls its glog equivalent. However, this enables us to migrate away from the gflags dependency and use Abseil flags. Once a follow-up change lands, `sapi::InitLogging()` will instead initialize the google logging library with flags defined from Aseil. Later still, once Abseil releases logging, we can then drop the glog dependency entirely. PiperOrigin-RevId: 445363592 Change-Id: Ia23a7dc88b8ffe65a422ea4d5233bba7bdd1303a
