[BREAKING CHANGE] Use new projection tooling for WinRT classes. WinRT APIs are
still in development and should be considered experimental; expect volatility
as the projection tools mature and map types like String and DateTime, as well
as WinRT primitives such as IVectorView, onto their Dart equivalents. (This
doesn't affect COM and Win32 APIs, which can largely be considered stable,
with the exception of changes to the underlying metadata exposed by
Microsoft.)
Add setupapi APIs, which were not being successfully projected. (#383, with
thanks to @Sunbreak.) Add test to prevent that happening again.
Add additional setup APIs (#386, with further thanks to @Sunbreak).
Remove tools/ folder from published package to reduce download overhead.
