Add a way to have out of source shell integrations

Some platforms (especially non-desktop ones) may use a custom
Wayland shell extension, more tailored to the form factor than
the generic and desktoppy wl_shell or xdg_shell. Instead of stuffing
N protocol implementations in the QPA plugin use a plugin architecture
to allow them to live out of tree.
When creating a shell surface the QT_WAYLAND_SHELL_INTEGRATION env
variable will be checked, and if it points to a valid plugin that
will be used to create the shell surface, falling back to wl_shell
or xdg_shell if no plugin is specified.
