Addon Vitest: Add experimental vitest integration

[kasperpeulen]

Closes #28388

What I did

This is the umbrella PR that will cover most of the work related to the Vitest integration project.

It includes a new Storybook addon called @storybook/experimental-addon-vitest, which currenly only includes a Vitest plugin. Later, it will include more functionality.

Additionally:

Core: Enable RSC support when parameters.react is set to true #28865

Now RSC can be enabled via parameters.react.rsc: true, as the flag is always on by default.

UI: Replace experimental_SIDEBAR_BOTTOM API with a status filter UI #28693

The bottom sidebar filter, which used to live in VTA, is now part of Storybook core. There should be no changes when using VTA with Storybook.

UI: Update sidebar status indicators and tooltips #28739

The status UI had a revamp with improved icons and styling.

Portable stories: Use internal Storybook renderers mechanism #28766

Portable stories now does not depend on testing-library.

Testing

This is extensively tested in unit tests and sandbox stories tests. If you want to test it yourself, there are a couple ways:
1 - Create any vite-based sandbox. It will already have the plugin set-up and you can just run yarn vitest to run tests in.
2 - On any vite-based Storybook, set up the addon via the npx storybook@next add @storybook/experimental-addon-vitest command
3 - On any vite-based Storybook, set up the addon by following the docs here https://web-git-8-3-pre-release-storybookjs.vercel.app/docs/8.3/writing-tests/test-runner-with-vitest from this PR: #28924

And run vitest to execute the tests. You can also test the VSCode/Jetbrains IDE integrations.

The changes in this PR are covered in the following automated tests:

• stories
• unit tests
• integration tests
