On systems where std::chrono::steady_clock::period is not std::nano, benchmark tests fail to compile due to trying to convert analysis.samples from a vector of duration<double, clock::period> to a vector of std::chrono::duration<double, std::nano>.

Description
On systems where std::chrono::steady_clock::period is not std::nano, benchmark tests fail to compile due to trying to convert analysis.samples from a vector of duration<double, clock::period> to a vector of std::chrono::duration<double, std::nano>.
To fix this, we instead construct a BenchmarkStats that matches the period of the clock. Once it's constructed, BenchmarkStats's conversion operator will handle converting to other durations.
