Use defineModel instead of custom useVModel composable

[mlmoravek]

Overview of the problem

Oruga version: [0.8.]
Vuejs version: [3.4.]

With several releases from 0.8.3 untill 0.8.10, we changed our custom useVModel composable to the Vue native defineModel implementation for bi-directional properties.

However, there are some issues with defineModel that prevent us from implementing further type support and enhancements.
Our component documentation process relies entirely on the vue-docgen-api. On #985 we have already enhanced it with a vue-component-meta integration, which allows us to use more modern Vue features.

But vue-component-meta cannot extract definModel js-doc comments, so we also have to define the property in defineProps with the js-doc comment ahead as well as in defineEmits, but also have defineModel for the implementation purpose.

Actual behavior

Now the problem we have is that Vue has some problems merging the defineProps with the defineModel type definition of a property that is typed by a component generic type.

This seems to be an known vue core issue and might be fixed with Vue 3.5 (vuejs/core#10801), but is not quite ready yet (vuejs/core#9652, vuejs/core#9277).

Therefore, I reverted some two-way-binded props with a custom useVModel composable in #998, which implements the bi-directional behaviour at runtime and is fully dependent on the defineProps and defineEmits definitions, instead of the compile-time definModel macro.

Expected behavior

The type of a property defined in both defineModel and defineProps will merge properly when using generic types.

Any bi-directional property should work with generic component types.
