Transform components imported by explicit import

[huang-julien]

Describe the feature

Currently it is not possible to have a server only component or client only component when importing them explicitly (such as import Client from '@/Client.client.vue' or import ServerComp from "../../ServerComp.server.vue".
Transforming them when explicitly imported makes more sense

This is a feature/fix that could possibly break some apps so it may be better to have it in nuxt 4.
