ModuleInterface: Only print API-level property wrappers in swiftinterfaces.

Browse Source 
When a function parameter has attached property wrappers (SE-0293) those
property wrappers are either considered "implementation" or "API" level.
Property wrappers that are implementation-level don't affect how the function
is called and therefore shouldn't be included in swiftinterfaces unless the
function's body is also printed.
