Remove custom testing and benchmarking code.

Snappy includes a testing framework, which implements a subset of the
Google Test API, and can be used when Google Test is not available.
Snappy also includes a micro-benchmark framework, which implements an
old version of the Google Benchmark API.

This CL replaces the custom test and micro-benchmark frameworks with
google/googletest and google/benchmark. The code is vendored in
third_party/ via git submodules. The setup is similar to google/crc32c
and google/leveldb.

This CL also updates the benchmarking code to the modern Google
Benchmark API.

Benchmark results are expected to be more precise, as the old framework
ran each benchmark with a fixed number of iterations, whereas Google
Benchmark keeps iterating until the noise is low.
