Components: Assess stabilization of View

[fullofcaffeine]

Issue: #59418.

What?

This is part of a larger effort to remove __experimental prefix from all "experimental" components, effectively promoting them to regular stable components. See the related issue for more context.

Why?

The strategy of prefixing exports with __experimental has become deprecated after the introduction of private APIs.

How?

1. Export it from components without the __experimental prefix;
2. Keep the old __experimental export for backwards compatibility;
3. Change all imports of the old __experimental in GB and components to the one without the prefix (including in storybook stories). Also, update the docs to refer to the new unprefixed component;
4. Add the component storybook id (get it from the storybook URL) to the PREVIOUSLY_EXPERIMENTAL_COMPONENTS const array in manager-head.html so that old experimental story paths are redirected to the new one;
5. Add a changelog for the change.

I think we should go with a passive deprecation on this one, since this is mostly used for the Emotion as prop, and we're moving away from both Emotion and as patterns. I don't think this ever has to be used anywhere.

We may have to eventually move to a stronger deprecation, depending on what we decide to do about Emotion/as.

@lena Thanks! What should we document in the deprecation comment as the alternative for this component?

AFAIU, this is already being passively deprecated as per #61099, no? Do you mean that we shouldn't re-report the unprefixed View? Also, what should we put in the deprecation message in that case?

Thanks!
