RegionalPrompting: Inherit from Stable Diffusion

[b-sai]

What does this PR do?

This pull request refactors the RegionalPromptingStableDiffusionPipeline class to inherit from the DiffusionPipeline class rather than the StableDiffusionPipeline class

I tested it on the examples here and it is replicating similar images

Fixes issue #6984

Hi @b-sai, thanks for the PR, can you please post an example with the images to ensure that this works? With this I mean to make sure that each region uses the corresponding prompt, it can be an easy one like a some geometrical figures with colors.
