[PATCH 0/1] MR1045: include: Add wine/winrt.h and define IInspectable helpers there.

[Paul Gofman (＠gofman)]

And use that instead of duplicating those helpers across the tree.

Besides removing existing duplicates, I am planning to add yet another WinRT dll (gamepad) and we will likely add more in the future, each of those can use that, as well as potentially more common helpers.
