refactor!: rewrite with improvements

[danielroe]

Description

This PR ended up being a little more than I had intended. In short, it:

1. switches to vitest
2. adds support for shouldPrefetch
3. moves publicPath to a function (buildAssetsURL) that is responsible for returning the public path of an asset - currently on rendererContext but it could easily be moved to ssrContext if we want per-request capability
4. normalises a 'parsed resource' type that is cached on rendererContext
5. removes unused _dynamicEntrypoints cache
6. does not prefetch prefetches of dynamic dependencies
7. does not also add preload tags for styles that should be rendered as well
8. adds more attributes to prefetch links
9. adds support for rendering preload/prefetch to headers (renderResourceHeaders)

Closes #28, resolves #20, resolves #24.

Breaking changes

• shouldPrefetch and shouldPreload now have a different function type: (resource: ParsedResource) => boolean
• createBundleRunner integration has been removed
• manifest is no longer normalized by default (instead users are recommended to normalise it themselves with normalizeClientManifest which can be imported from vue-bundle-renderer/legacy)
• clientManifest and publicPath options can no longer be provided to createRenderer

Hi @danielroe @pi0, is there any plan to merge this PR on future? I'm facing the issue with prefetch nuxt/nuxt#14093. Hope this PR can fix our problem 🌟

Is there any movement for this? We'd love to see that sooner - for our APP see all chunks preloaded is really a blocker.
