Added a bool to allow the node user to add noise in to initial latents (default) or to leave them alone.

I went ahead and made a small change in eaf4e08. Other than that, LGTM. I smoke tested text-to-image and image-to-image. |

Summary
The Flux VAE, like many VAEs, is broken if run using float16 inputs returning black images due to NaNs
This will fix the issue by forcing the VAE to run in bfloat16 or float32 were compatible
Related Issues / Discussions
Fix for issue #7208
QA Instructions
Tested on MacOS, VAE works with float16 in the invoke.yaml and left to default.
I also briefly forced it down the float32 route to check that to.
Needs testing on CUDA / ROCm
Merge Plan
It should be a straight forward merge,
