[API Proposal]: Change accessibility of System.Random's implementation

[Xyncgas]

Background and motivation

Perhaps, while people can choose to use new System.Random() or System.Random.Shared, let it be possible to choose which implementation we are going to use, for example let people do new System.Random.Xorshiro()

Currently the actual name for the Xor shift rotation implementation in System.Random is XoshiroImpl and it's an internal class

I personally get something out of this if I can use specifically the flavor I'd like for my rng, because it's now possible to System.Random.Xorshiro().Seed(State), Initializing it with a state that was maybe extracted from State property

API Proposal

public sealed class XorShiro: ImplBase
{
...
public void Seed(){}
public static Random Seed(State state){}
public State State (){}
}

API Usage

var automaticAlgorithm = System.Random.Shared;

var manualAlgorithm = System.Random.XorShiro.Seed( :Span / number / state);
var state = manualAlgorithm.State;

for (var i = 0; i < 3; i++) manualAlgorithm.Next(); //1,1,1

var restore = System.Random.XorShiro.Seed(state);

for (var i = 0; i < 3; i++) restore.Next(); //1,1,1

Alternative Designs

Have people implement their own rng
