`VaSelect` tagging state feature

We have something similar, but

Needs research.

• Not sure if we want to use separate component or the same one?

• Maybe we can also set default values for docs examples, so that tags are visible for users.

All other frameworks (vuetify, quasar, mui, ant) are simply using chips inside select components for this purpose. So, i will just update our documentation to highlight this feature.
