Andreas Haas e9d02eb56e [benchmark] Fix C++ benchmarks build in a Chrome checkout
Update test/benchmarks/cpp/BUILD.gn and test/benchmarks/cpp/cppgc/BUILD.gn
so that fast_api_benchmark and other C++ benchmarks can be built in a
Chrome checkout (build_with_chromium) in addition to a standalone V8
checkout:

- Use relative paths (../../..:v8, ../../..:v8_libbase, etc.) instead of
  root-relative paths (//:v8) which point to the Chromium root in a
  Chrome checkout.
- Add ../../..:internal_config_base to benchmark targets so V8 include
  paths are configured when building in Chromium.
- Depend on //third_party/google_benchmark when build_with_chromium is
  true instead of //third_party/google_benchmark_chrome.
- Add //build/config/compiler:no_exit_time_destructors to cppgc
  benchmarks.
- Include "benchmark/benchmark.h" via the benchmark_config include_dirs
  instead of hardcoding the third_party/google_benchmark_chrome path.
