[FEAT] Add support to Wayland

[btd1337]

Hi devs,

As you can see, Wayland is taking your space and the new Ubuntu version will already come as default.

Could you support him?

For software like docks that integrates with the window manager, it is important to ask "which wayland (compositor)"?

I really recommend that the elementary team consider the wlroots approach, which has protocols in place for panels and docks to integrate with the compositor/WM. A couple examples are:

1. wlr_foreign_toplevel_management_unstable_v1, which claims "to enable the creation of taskbars and docks by providing them with a list of opened applications and letting them request certain actions on them, like maximizing, etc."
2. wlr_layer_shell_unstable_v1, which claims that it "should be suitable for the implementation of many desktop shell components, and a broad number of other applications that interact with the desktop"
