Documentation using vue-component-meta

[mlmoravek]

Description

Currently the components are documented using Vue Styleguidist and vue-docgen-cli.
However, they lack compatibility with modern Vue features such as script setup with generics and defineModel support.

vue-component-meta is a port of the vue language toolkit which can be used to extract information about a component. vue-component-metacan be used to parse the component props and extract documentation information.

Proposed change:

Extend the vue-docgen process by inclduing vue-component-meta information to allow the use of modern vue features without sacrificing documentation flexibility.

(This will make type-based declaration approach with the withDefaults compiler macro usable to implement proper conditional types #835)

Why Oruga need this feature

Improve documentation and use modern Vue features for documentation.
