The Clang importer maps arbitrary attributes spelled with `swift_attr("...")`
over to Swift attributes, using the Swift parser to process those attributes.
Extend this mechanism to allow `swift_attr` to refer to an attached macro,
expanding that macro as needed.
When a macro is applied to an imported declaration, that declaration is
pretty-printed (from the C++ AST) to provide to the macro implementation.
There are a few games we need to place to resolve the macro, and a few more
to lazily perform pretty-printing and adjust source locations to get the
right information to the macro, but this demonstrates that we could
take this path.
As an example, we use this mechanism to add an `async` version of a C
function that delivers its result via completion handler, using the
`@AddAsync` example macro implementation from the swift-syntax
repository.
