[WIN32SS][NTDDRAW][NTGDI] Implement some DxEng* callbacks (#3638) 
Implement the following DxEng* functions:
- DxEngAltLockSurface
- DxEngDeleteSurface
- DxEngReferenceHdev
- DxEngSelectBitmap
- DxEngSetBitmapOwner
- DxEngUnreferenceHdev

Update their prototypes and call the appropriate win32k functions
inside them, since they are already implemented. Also get rid of
now unused IntGdi(Un)ReferencePdev, whose were called only by dxeng,
and whose are not used anymore. In Windows, DxEng(Un)ReferenceHdev calls
PDEVOBJ_vReferencePDEV and PDEVOBJ_vDeferencePDEV directly (those
correspond to our PDEVOBJ_vReference and PDEVOBJ_vRelease accordingly).

Required by MS DirectDraw stack (ddraw.dll & dxg.sys). CORE-17561
