wined3d: Enabling too many lights is silently ignored.

I'm resending this patch because my reply to Henri's concern came too late.
Henri noted that I am enabling lights that do not exist. Existing tests show
that if no light is assigned to the index, LightEnable creates a light with a
set of default parameters, so the tests should be fine.

Subject: [PATCH] WineD3D: Enabling too many lights is silently ignored

This patch adds tests for all d3d versions that show that Windows
pretends that enabling more lights than supported succeeds. D3D_OK is
returned, and the light is reported as enabled.

What is not tested in this patch is the rendering output of this
situation, thus the FIXME is still written.
