write iasync info

[stevenbrix]

IAsyncInfo is a special interface with it's own header file (much like IInspectable). This nuance makes it annoying to work with and so before we just didn't try writing the type.

Changes

1. remove include of AsyncInfo.h and remove special checks for the type so that we can let our code-gen do it's thing

Fixes WIN-103

WIN-103 Write IAsyncInfo

IAsyncInfo is a manually written type. We don't generate wrappers for it and therefore can't implement it yet in swift

Just realizing this approach with the checked in hand written file might be silly and can just let the c code generator generate the definitions for these types

If there's nothing preventing that, it would be a better approach. I'm surprised it would require so much special-casing.

@tristanlabelle nope! nothing preventing it, latest update removed the handwritten version
