[Coroutines][NFC] Remove @llvm.coro.id.async intrinsics from CoroElide

[yuxuanchen1997]

Easy change. There's no mentioning of coro.id.async in the pass. The check follow immediately after this is hasCoroIds. We are wasting cycles counting coro.id instructions when compiling non-switch ABI coroutines. Cleaning this up.
