Along with the mini_chromium /bigobj fix, this allows us to build and run
gtest’s and gmock’s own tests, so that we can see that they’re actually working

ninja -C out\Debug_x64 gtest_all_tests gmock_all_tests
out\Debug_x64\gtest_all_test
out\Debug_x64\gmock_all_test
rem out\Debug_x64\gtest_*_test and out\Debug_x64\gmock_*_test too
