merge revision(s) 54144: [Backport #12139]
* lib/securerandom.rb (gen_random): to avoid blocking on Windows.
On Windows OpenSSL RAND_bytes (underlying implementation is
RAND_poll in crypto/rand/rand_win.c) may be blocked at
NetStatisticsGet.
https://wiki.openssl.org/index.php/Random_Numbers#Windows_Issues
Instead of this, use Random.raw_seed directory (whose implementation
CryptGenRandom is one of the source of
entropy of RAND_poll on Windows).
https://wiki.openssl.org/index.php/Random_Numbers
Note: CryptGenRandom function is PRNG and doesn't check its entropy,
so it won't block. [Bug #12139]
