oleaut32/tests: Add a test to show that support for coercion to arrays of variants is specific to vararg methods.

This time with passing SAFEARRAY as a reference.

Same patch as just a minute ago, alas fro d3d9 instead of d3d8.

The intent is to eventually eliminate wined3d_resource_from_d3d10_resource().

They're non-functional these days anyway.
