[PATCH v2 1/2] makedep: Add support for generating winmd files.

[Hans Leidekker]

From: Hans Leidekker

Note that this treats winmd files as architecture independent data files even
though native stores them in both system32/winmetadata and syswow64/winmetadata.
They are 32-bit dlls in both locations and while there are small differences in
file sizes their content is not materially different.
