LibCore+LibGUI: Add fallible versions of Widget::load_from_gml()

Browse source 
The existing `load_from_gml()` methods look the same as before from the
outside. Inside though, they now forward to `try_load_from_gml()` which
returns Error when things go wrong. It also now calls the `try_create()`
factory method for Objects instead of the `construct()` one.
