codegen: LX424 Generate code for WSI-specific funs in GIPA.

For the unique_objects and object_tracker layers, generate
system types (xcb, xlib, wayland, mir) in GetInstanceProcAddr.
The previous code would only generate code for one display
system, even if more than one was selected by the CMake config.
The code to return these proc addresses is conditionally compiled
with the corresponding USE_PLATFORM #ifdef, and the CMake config
can go ahead and set multiple USE_PLATFORM defines.
The result is that GIPA resolves proc address requests for these
functions and allows them to be hooked properly when the layers
are loaded.
