[Feature request]: Add Kolors Support

It is SDXL architecture with a different noise scheduler(Kolors Scheduler?) and text encoder (ChatGLM3-base).

Would be great to be able to fine tune it as it is better than any other openly available base model now.

Start by reviewing the Kolors repository linked in the issue and compare its SDXL architecture, noise scheduler, and ChatGLM3-base text encoder with this project's existing support. The issue does not name files or tests; define the required integration points and verify that Kolors can be fine-tuned successfully.
