feat(package): add unimport presets and unplugin-vue-components resolvers

[userquin]

Description

Last PR to include node stuff: this PR can be closed once merged #20536

Both subpackage exports ESM-only, if you want to use dual ESM/CJS ping me...

I need to do some tests...

• ✔️ Nuxt working, check chore: use local Vuetify dev tgz from Vuetify #21129 PR userquin/vuetify-nuxt-3.16-lazy-hydration#3 => dev-pr-21129 branch
• ✔️ Vite + unplugin-vue-components working: https://github.com/userquin/check-vuetify-unplugin-vue-components-2 (the directives works only via unimport preset)

Markup:

NA

should we add component prefix support here?

[userquin]

At this point I want to create also custom vuetify styles plugin using unplugin, this way we can also support other bundlers "for free" (🤞 ). I guess at this point this PR should be moved to loader repo as a new package with 3/4 sub-package exports, unimport preset, unplugin-vue-components resolvers, unplugin styles plugin (default) and maybe utils with some exports from the utils.ts module here.

Kael, we should move the repo to pnpm workspaces using pnpm catalogs (VSCode pnpm lens plugin), 30 minutes to add dependencies to the new package ;)

New @unvuetify/monorepo repository created and initial packages versions published, we'll have some more Vite/Nuxt utilities in this new repository
