Attention processors that do not expect a `temb` parameter still get passed them and cause TypeErrors

[lsb]

Describe the bug

The parameterized attention is always passed a temb keyword argument, and many attention processors do not expect it, causing a type error.

A (currently incomplete) fix for this is #6687

Reproduction

from diffusers import DiffusionPipeline
from diffusers.models.attention_processor import SlicedAttnProcessor

pipe = DiffusionPipeline.from_pretrained(
"hf-internal-testing/tiny-stable-diffusion-torch",
)

pipe(prompt="a trout", num_inference_steps=1).images[0].save("trout1.png")

pipe.vae.set_attn_processor(SlicedAttnProcessor(1))

pipe(prompt="a trout", num_inference_steps=1).images[0].save("trout2.png")
