Joachim Henze 81cffd7658 [D3D8][D3D9][DDRAW][D3DCOMPILER_43][WINED3D] Revert to Wine Staging 3.3 
Avoid regressions CORE-14955 "Ddraw fullscreen crashes" and CORE-15652

This brings us back to before guilty commit 0.4.10-dev-55-g
7af3969e9f

and therefore downgrades
dll/directx/wine/
D3D8,D3D9,DDRAW,D3DCOMPILER_43,WINED3D
to WineStaging 3.3.
Also downgrades related header sdk/include/reactos/wine/wined3d.h
and for the first time also media/doc/README.WINE

Same versions of these dlls we had in every ros rls since 0.4.10rls.
Amine Khaldi agreed to perform this revert also for master now.

Purpose of this revert is to fix crashes when Ddraw apps switch
into fullscreen with VBEMP and inbuilt Mesa.
I tested, before:
 DxDiag crashed when switching to fullscreen (CORE-14955),
 Diablo II crashed immediately (CORE-15652),
 Monster-Truck-Madness 2 demo crashed after main menu

Afterwards all of these apps do run.
DXTN does still work after that, even with VBEMP and inbuilt Mesa.

squashed commit of 0.4.13-RC-2-g
67dd70e5ef
and 0.4.13-RC-3-g

/* GL_ATI_fragment_shader always supports 6 textures, which was the limit on r200 cards
* which this extension is exclusively focused on(later cards have GL_ARB_fragment_program).
* If the current card has more than 8 fixed function textures in OpenGL's regular fixed
* function pipeline then the ATI_fragment_shader backend imposes a stricter limit. This
* shouldn't be too hard since Nvidia cards have a limit of 4 textures with the default ffp
* pipeline, and almost all games are happy with that. We can however support up to 8
* texture stages because we have a 2nd pass limit of 8 instructions, and per stage we use
* only 1 instruction.
*
* The proper fix for this is not to use GL_ATI_fragment_shader on cards newer than the
* r200 series and use an ARB or GLSL shader instead
