feat(vue3 compiler): use setup instead data (options api can be disabled)

[userquin]

Description

Looks like the idMap isn't available in the _ctx, the data() included inside the options.

This PR also fixes Vue 2 cli example: we need to use .default in webpack plugin and also add vue-template-compiler dev dependency: https://stackblitz.com/edit/unplugin-unplugin-icons-pql4wz?file=package.json

NOTE: the reproduction disabling options api (features: { optionsAPI: false },) in the Vite Vue plugin: that's why data not available in the render function.

This PR includes the vscode python icon in the linked reproduction in all vue examples (working in all examples 🤔 ).
