wined3d: Only update the swizzle and use map for streams that are actually used in device_stream_info_from_strided().

This fixes a regression introduced by d7c7c768
and exposed by ef2d7041. Unfortunately having
EXT_vertex_array_bgra support masks the problem, which is why the regression
tests didn't catch it.

rpcrt4: Factor out non-Win32 compatible parts of the ncacn_ip_tcp client code to allow it to be compiled in.

Instead of the usage token.

Just a change in name to prepare for the next patch
