[PATCH 1/6] widl: Print full namespace name on error.

[Rémi Bernon]

Not really necessary as the errors are usually more cryptic, but nice
to have when it fails there.

This series is just implementing a little better support of WinRT-style
interfaces in idl files, required for cleaner stubbing of some WinRT
dlls, which are in turn, necessary for some recent games to even start.

Namely, Death Stranding requires windows.gaming.input.dll, and
Flight Simulator requires windows.media.speech.dll, where some simple
stubs are enough to make both happy.
