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.

This change starts with Jsonnet as the canonical, ready-made sandboxed library
example. Follow-up changes should similarly migrate the OSS Internship
sandboxes.
- Add an `add_sapi_subdirectory()` which sets up source and binary directories
correctly when consuming SAPI as sub-project
- Restructure the Jsonnet `CMakeLists.txt` and simplify header inclusions
- Update the Jsonnet README file
