Migrate third_party/ to git submodules.

This replaces third_party/absl/ and third_party/protobuf-lite/ with
submodules checked out at specific versions for abseil-cpp, googletest,
benchmark, and protobuf libraries.

This change allows removing local code copies of absl and googltest
functionality.
