Adding a Pipewire application profile (#821)

* Adding a Pipewire application profile

This to better manage the pipewire setup process and minimize guided a bit. This also adds the concept of @archinstall.plugin decorators to add a plugin in run-time. Which pipewire uses to detect user creation and enable the pipewire-pulse service for new users.

* Forgot to run .install() on pipewire Application()
* Backwards compatible variable insertion for installation session
