Description

Please, see discussion in #2155. I was under the wrong assumption that FlaxLMSDiscreteScheduler had been made jittable as part of #1661, but it never was.

Research direction
Investigate the current implementation of FlaxLMSDiscreteScheduler in the diffusers repository. Review the discussion in issue #2155 and the previous PR #1661 to understand what was attempted. Look at other Flax schedulers that are already jittable to understand the pattern. Implement jit compilation for the scheduler, ensuring all operations are compatible with JAX's jit transformation.
