Allow normal function results of @yield_once coroutines (#69843)

Browse Source 
This adds SIL-level support and LLVM codegen for normal results of a coroutine.

The main user of this will be autodiff as VJP of a coroutine must be a coroutine itself (in order to produce the yielded result) and return a pullback closure as a normal result.

For now only direct results are supported, but this seems to be enough for autodiff purposes.
