add `Vue` module augmentation for directives

[userquin]

Clear and concise description of the problem

To allow VSCode (Volar) suggesting directives we need to augment vue module using GlobalDirectives: @BobbieGoede and me are checking if we also need ComponentCustomProperties (looks like Volar still needs it).

Suggested solution

Augment Vue module per directive, maybe we can do that in the build script.

Alternative

Add the Vue module augmentation manually per used directive.

Or add it to unplugin-vue-components: right now there is an existing vueuse-directive but for the component usage (?)

Additional context

You can check feat(addon): add auto-import vue directives on unimport repo to allow auto importing vue directives including also dts declaration.
