* Initial attempt at merging Interop types into the main winmd.
The winmd is generated but the attributes don't appear to be retaining the Attribute inheritance which is causing build failures in the WinmdGenerator and samples.
* Updated new files and attributes.
* Updated interop reference.
* Attributes moved to Windows.Win32.Foundation.Metadata and everything builds and compiles but attributes that expose properties like MemorySize and NativeArrayInfo have questionable definitions since the properties aren't exposed in the metadata.
* Updated debug configuration.
* Added support for properties and attributes.
* Updated the baseline.
* Added public constructors.
* Updated the diffing tool to account for the attribute namespace change and updated the baseline.
