clarencechen c6e56e92ed Add Recent Timestep Scheduling Improvements to DDIM Inverse Scheduler (#3865)
* Add Recent Timestep Scheduling Improvements to DDIM Inverse Scheduler

Roll timesteps by one to reflect origin-destination semantic discrepancy

Restore `set_alpha_to_one` option to handle negative initial timesteps

Remove `set_alpha_to_zero` option not used due to previous truncation

* Bugfix

* Remove unnecessary calls to `detach()`

Use `self.image_processor.preprocess` in DiffEdit pipeline functions

* Preprocess list input for inverted image latents in diffedit pipeline

* Add `timestep_spacing` and `steps_offset` to `DPMSolverMultistepInverseScheduler`

* Update expected test results to account for inverting last forward diffusion step

* Fix inversion progress bar bug

* Add first draft for proper fast tests for DDIMInverseScheduler

* Add deprecated DDIMInverseScheduler kwarg to ConfigMixer registry

* Fix test failure in DPMMultistepInverseScheduler

Invert step specification leads to negative noise variance in SDE-based algs

Add first draft for proper fast tests for DPMMultistepInverseScheduler

* Update expected test results to account for inverting last forward diffusion step

Clean up diffedit fast test
