Add a mechanism that detects via the version resource whether it's needed to mirror
the application layout or not. This is a "follow up" to commit 5b14b6f.
This code is taken from the GetProcessDefaultLayout() function from Wine
(called there "WIN_CreateWindowEx").
In Windows the version-resource mirroring happens when the GDI is loading the LPK.
- Implement mirroring via version resource. GDI linking on startup is required.
- GDI32: Add LPK loading on GDI startup.
To enable mirroring via version resource the lpk.dll must be loaded before any windows are created.
This is done through GdiInitializeLanguagePack() function which is called in GdiProcessSetup().
- LPK: Use Wine debug messaging.
