coroutine: annotate coroutine_fn for libclang
Clang has a generic __annotate__ attribute that can be used by static analyzers to understand properties of functions and analyze the control flow. Furthermore, unlike TSA annotations, the __annotate__ attribute applies to function pointers as well. As a first step towards static analysis of coroutine_fn markers, attach the attribute to the marker when compiling with clang.
