[SUA][IRGen] Change IRGen to emit calls to swift_coroFrameAlloc (#79384)

Browse Source 
When TMO is enabled, change IRGen to pass the newly introduced runtime function `swift_coroFrameAlloc` (and pass an additional argument — the hash value) instead of `malloc` when it inserts calls to `coro_id_retcon_once`.
The hashValue is computed based on the  current function name (computed in `getDiscriminatorForString`)
