Support generating @MainActor annotations #149

Closed tristanlabelle closed 2 months ago

tristanlabelle commented 5 months ago

Two possible implementations:

Support Swift.MainActorAttribute which could be applicable to classes, interfaces, delegates, methods and properties.
Extend projection.json to list @MainActor types (retrocompatible with UWP APIs)

Let's consider this done with the custom Swift attribute support. Retroactively applying @MainActor to existing WinRT APIs might not be implementable because of the transitive effect of this attribute on any function taking a @MainActor class object as a parameter.
