📚 Description

This PR upgrades Bridge to Vite 3.

Note: Because it covers a lot of the same files as https://github.com/nuxt/bridge/pull/476, I've taken the liberty of squashing that PR into the base of this one. I'll rebase after it merges.

There are quite a few fixes/refactors to note, including some other vite fixes in Nuxt 3 that we're hereby porting back to Bridge. But particularly worth observing:

1. We remove the workaround where we move build output files around, instead modifying chunk names.

2. We remove our runtime URL implementation, using new Vite support from https://github.com/vitejs/vite/pull/8450.

   We'll track the development of this feature quite closely as it moves from experimental into the mainstream, but it will not break in a minor version so the current version constraint is safe.

👉 Migration

Vite 3 is a major release with its own breaking changes. Users should read through the migration guide and make any updates necessary. (Other libraries may also have to be updated to work with Vite 3.)

There are no Nuxt-specific changes that users will need to make.
