rand: deprecate `rng`.
This should be called far less than it is because it does expensive OS interactions and seeding of the internal RNG, `task_rng` amortises this cost. The main problem is the name is so short and suggestive. The direct equivalent is `StdRng::new`, which does precisely the same thing. The deprecation will make migrating away from the function easier.
