Windows: use modern API to gather system entropy for random generation instead of obsolete that were not working This commit increases randomness quality by using more dynamic/varied sources of entropy. PDH-based disk and network statistics collection in now added to random pool - Introduced `GetDiskStatistics` to gather disk read/write performance data using PDH API. - Introduced `GetNetworkStatistics` to gather network send/receive performance data using PDH API. - Integrated high-resolution timestamps and random intervals to improve entropy in collected data. - Updated `SlowPoll` function to utilize PDH-based disk and network statistics. - Removed obsolete NetAPI32-based network statistics collection.
