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.

`BUILD_TESTING` is a CMake provided option and we should use similar naming,
just like how Abseil does it.
- `SAPI_ENABLE_TESTS` -> `SAPI_BUILD_TESTING`
- `SAPI_ENABLE_CONTRIB_TESTS` -> `SAPI_CONTRIB_BUILD_TESTING`
- `SAPI_ENABLE_EXAMPLES` -> `SAPI_BUILD_EXAMPLES`
