On Build error xcopy on not english localized machines

[DieselMeister]

On a non english localized machine the xcopy command lines in the file:

cppwinrt.build.post.props

generate an error while building.

the "echo f" in front of the 4 commands (look for xcopy) works only if the word "file" in your language begins also with an "f".

In germany it's a "D" for "Datei".

wait really

That seems insane to me, but that can be fixed. echo f | xcopy always seemed like a hack to me anyways.

We should address this by removing manual xcopy steps :)

Or use robocopy, which should have the same command syntax for all languages.
