panel & taskpanel: Port to use plasma_add_applet

Use plasma_add_applet to deploy the applets as a module: https://invent.kde.org/plasma/libplasma/-/merge_requests/1116

We eventually need to do this for Halcyon and Folio homescreens too, but
they also have a bunch of C++ classes to be ported to declarative type
registration.
