wayland: Allow the creation of roleless window surfaces for custom application use

Browse Source 
Allow for the creation of SDL windows with a roleless surface that applications can use for their own purposes, such as with a windowing protocol other than XDG toplevel.

The property `wayland.surface_role_custom` will create a window with a surface that SDL can render to and handles input for, but is not associated with a toplevel window, so applications can use it for their own, custom purposes (e.g. wlr_layer_shell).

A test/minimal example is included in tests/testwaylandcustom.c
