* initial commit for LatentConsistencyModelPipeline and LCMScheduler based on the community pipeline

* Add callback and freeu support.

* apply suggestions from review

* Clean up LCMScheduler

* Remove timeindex argument to LCMScheduler.step.

* Add support for clipping or thresholding the predicted original sample.

* Remove unused methods and arguments in LCMScheduler.

* Improve comment about (lack of) negative prompt support.

* Change input guidance_scale to match the StableDiffusionPipeline (Imagen) CFG formulation.

* Move lcm_origin_steps from pipeline __call__ to LCMScheduler.__init__/config (as origin_steps).

* Fix typo when clipping/thresholding in LCMScheduler.

* Add some initial LCMScheduler tests.

* add type annotations from review

* Fix type annotation bug.

* Override test_add_noise_device in LCMSchedulerTest since hardcoded timesteps doesn't work under default settings.

* Add generator argument pipeline prepare_latents call.

* Cast LCMScheduler.timesteps to long in set_timesteps.

* Add onestep and multistep full loop scheduler tests.

* Set default height/width to None and don't hardcode guidance scale embedding dim.

* Add initial LatentConsistencyPipeline fast and slow tests.

* Add initial documentation for LatentConsistencyModelPipeline and LCMScheduler.

* Make remaining failing fast tests pass.

* make style

* Make original_inference_steps configurable from pipeline __call__ again.

* make style

* Remove guidance_rescale arg from pipeline __call__ since LCM currently doesn't support CFG.

* Make LCMScheduler defaults match config of LCM_Dreamshaper_v7 checkpoint.

* Fix LatentConsistencyPipeline slow tests and add dummy expected slices.

* Add checks for original_steps in LCMScheduler.set_timesteps.

* make fix-copies

* Improve LatentConsistencyModelPipeline docs.
