This version supports seeding generation, for more see: - #335 On TVMjs side, we make the runtime seedable via: - apache/tvm#16722

…pache#16722) This PR implements `LinearCongruentialGenerator` in TVMjs, following the C++ counterpart in apache#8642. The motivation is that we want to seed autoregressive generation to make results reproducible, supporting the OpenAI field `seed`. The main function is `nextInt()`, which generates a number `(0, 2^32 - 1)` non-inclusive. Subsequently, we change all `Math.random()` in `runtime.ts` to `this.rng.randomFloat()`, exposing API `Instance.setSeed()`. Unit tests are added for `LinearCongruentialGenerator` for testing seed and coverage.
