Move Godot Physics 3D into a module; add dummy 3D physics server

If the module is enabled (default), 3D physics works as it did before.

If the module is disabled and no other 3D physics server is registered
(via a module or GDExtension), then we fall back to a dummy
implementation which effectively disables 3D physics functionality (and
a warning is printed).

The dummy 3D physics server can also be selected explicitly, in which
case no warning is printed.
