[PATCH 2/5] wined3d: Allow all formats with "glInternal" set in CheckSurfaceCapability().

[Henri Verbeet]

Rendertarget, depth/stencil and texturing restrictions are applied later in
wined3d_check_device_format(), so to the extent this make a difference it
mostly affects off-screen plain surfaces. Note that if the blitter check were
to be implemented properly it would practically always return TRUE as well,
because of the CPU based blitter.
