refactor(ww3d2): Widen IRenderBackend draw arguments to 32 bits

[bobtista]

• Follow up for refactor(ww3d2): Route render-target binding via IRenderBackend #3424

Draw_Triangles, Draw_Strip and Set_Index_Buffer on IRenderBackend take 16-bit start index, counts, vertex range and index base offset, because that is what the DX8Wrapper signatures take.

Now the interface takes 32-bit values. DX8Backend narrows them to 16 bits and asserts that nothing was lost. Release builds narrow exactly as before. Debug builds now assert where a caller passes a value above 65535, which the old implicit conversion truncated silently.

Todo:

• Build win32 and vc6, including W3DView and WorldBuilder
• Load two skirmish saves and the shell map, open W3DView through its device dialog, and open WorldBuilder. Same result as main
• Load two skirmish saves in a debug build. No assertion from the backend
• Replicate to Generals
