removal of the last few deprecations for 7.0

@shilman Do you think you can help me understand why https://app.circleci.com/pipelines/github/storybookjs/storybook/30614/workflows/4a03924c-4716-4d9e-ac10-c499ba5fdae8/jobs/429471 is failing? Seems the background color isn't applied anymore, but I can't seem to find the reason why.

@tmeasday you marked adding unknown globals as deprecated, but it looks like removing that actually breaks addon-backgrounds?

Well yeah, I guess backgrounds should export a globalTypes definition for BACKGROUNDS_PARAM_KEY ('backgrounds')

[ndelangen]

That fixed it @tmeasday ♥️

@shilman mentioned that he wanted to discuss this deprecation further.

He said that silently ignoring new incoming properties was not a good idea. I tend to agree.
We should either fail hard or continue to warn.

I'll add a bit of code that throws an error when a property is filtered out

@tmeasday can you chime in on why we want to force addons to declare their globalTypes before using them? it makes sense intuitively, but is there some specific use case or problem that you have in mind? Just curious to help me understand the change better. Thanks!

@shilman, according to the original commit:

This ensures weird stuff doesn't happen when we change arg/global names.

I don't really have any recollection of it, to be honest. I don't feel strongly about it.

@tmeasday thanks, just checking. i think we should do it FWIW.
