Fix 'experimental/coroutine' file not found on macOS (#5030) (#5031) (#5151)

Browse Source 
libcxx has removed the experimental/coroutine include file in favor of
the C++20-standard coroutine include. If the latter is available we
use it otherwise falling back to the existing experimental version (in
which case we also disable the deprecated-experimental-coroutine warning).

(See also https://reviews.llvm.org/D108697.)
