Seed the random number generator in Windows with rand_s

Provide more accurate results about used heap size via GetHeapStatistics.

I observed that used heap size provided by Heap::SizeOfObjects() is
usually about ~10% bigger than the number calculated by summing up
heap objects sizes.

This aligns DevTools Timeline stats with Heap profiler stats.
