CHEN Feng a1678b2278 thirdparty: migrate benchmark to vcpkg (pinned 1.7.1) (#186) ...

Replace the vendored google/benchmark 1.5.3 foreign build with a thin
vcpkg wrapper. Consumers keep depending on //thirdparty/benchmark:{benchmark,
benchmark_main}; cc_config.benchmark_libs / benchmark_main_libs are unchanged.

Pinned to 1.7.1: 1.8.0 deprecated benchmark::DoNotOptimize(const T&), which
flare's *_benchmark.cc use heavily, and flare builds gcc with
-Werror=deprecated-declarations (clang/macOS doesn't trigger it). 1.7.1 is the
last series before that deprecation.

vcpkg ships benchmark at its native include/benchmark/ layout, so no
include_prefix is needed. Drops the vendored tarball and the
remove_unused_var.patch.
