James Tucker 24bac27632 util/rands: add Shuffle and Perm functions with on-stack RNG state ... The new math/rand/v2 package includes an m-local global random number generator that can not be reseeded by the user, which is suitable for most uses without the RNG pools we have in a number of areas of the code base. The new API still does not have an allocation-free way of performing a seeded operations, due to the long term compiler bug around interface parameter escapes, and the Source interface. This change introduces the two APIs that math/rand/v2 can not yet replace efficiently: seeded Perm() and Shuffle() operations. This implementation chooses to use the PCG random source from math/rand/v2, as with sufficient compiler optimization, this source should boil down to only two on-stack registers for random state under ideal conditions.
