📚 Description

Hello 👋,

This PR allows modules developers to add references or tweak the tsconfig file before saving it.

I also refactor how references are build to easily add a new one (just a path).

This hook is similar to the one in Nuxt.

types:extend hook was added via #1715 to allow extending types via a hook (#1710)

Allow extending more items like declarations is good idea, thinking to do few structure changes to allow it (we don't need a new hook, i hope)

Still in my module, explained here #2506 (comment)

Yes! My TypeScript knowledge led me updating what I thought was the main file .nuxt/nuxt.d.ts to augment Nuxt and Vue types. After, I tried to do the same to Nitro but it was not possible so I propose this change, similar to the current behavior of Nuxt.

But, after deep diving into the tsconfig file and the files created by Nuxt, it seems that Nuxt automatically add a path to the current module and because it's a directory, it's possible to add .d.ts file which is way more elegant than a template file since it's not dynamic.

The Nuxt module author guide, https://nuxt.com/docs/guide/going-further/modules#adding-type-declarations, is very misleading about the usage of template so typescript and I will open an issue.

While writing these lines, I haven't check if Nitro add a similar line, a reference to the module to allow .d.ts, or if it's come from Nuxt but it could help to have the same (well documented) in Nitro. But there is still the question for dynamic .d.ts file, like the one Nitro generate for the app.config or the routes definitions.
