rand: add methods to allow greater control over `PCGSource`
For golang/go#49934.
Add two methods to PCGSource, Seed128 and State.
The standard Seed method only allows seeding with a uint64, but the PCG internal state is, effectively, a uint128. Seed128 allows the user to pass both the high and low bits for this state as two uint64s, allowing much greater control over the generator's state.
State does the opposite, returning the entire 128-bit state as two uint64s.
Should that be Seed128() instead? It's allowing you to set 128 bits of the generator's state, not 64.
