D3D8: For render states D3DRS_POINTSPRITEENABLE and D3DRS_MULTISAMPLEANTIALIAS, use GL_SUPPORT correctly

[H. Verbeet]

GL_SUPPORT should be used with a member of the GL_SupportedExt enum.
Neither GL_ARB_point_sprite nor GL_ARB_multisample are. Also, there is
no reason to even look at "Value" if an extension isn't supported.

Changelog:
  - Use GL_SUPPORT correctly
  - Don't check Value before checking the required extension is supported.
