SDL_LEAN_AND_MEAN broken by recent update to SDL_render_d3d.c (e1fde46a)

[definability]

Got this error when compiling the current main (87f9a0e) on Windows using CLang 20:

SDL\src\render\direct3d\SDL_render_d3d.c(1062): error C2039: 'yuv': is not a member of 'D3D_TextureData'
SDL\src\render\direct3d\SDL_render_d3d.c(99): note: see declaration of 'D3D_TextureData'

Looks like #12578.
