Merge #15250: Use RdSeed when available, and reduce RdRand load
1435fabc19d2143187efb493cbe23225eaf851ae Use RdSeed when available, and reduce RdRand load (Pieter Wuille)
Pull request description:
This introduces support for autodetecting and using the RdSeed instruction on x86/x86_64 systems.
In addition:
* In SeedFast, only 64 bits of entropy are generated through RdRand (256 was relatively slow).
* In SeedStartup, 256 bits of entropy are generated, using RdSeed (preferably) or RdRand (otherwise).
