What does this PR do?
Prevents crashing on system with low ram during load of SDXL models by deferring the unet's transfer to cpu till after tokenizers etc are loaded., right before constructing the pipe. Unless the loads are correlated in some way or I missed some important function in the middle, this should have the same effect and leave only torch to deal with a complete lack of memory.
