  -----------
  [Coroutines] ABI Objects to improve code separation between different ABIs, users and utilities. (#109338)

* Adds an ABI object class hierarchy to implement the coroutine ABIs
(Switch, Asyc, and Retcon{Once})
* The ABI object improves the separation of the code related to users,
ABIs and utilities.
* No code changes are required by any existing users.
* Each ABI overrides delegate methods for initialization, building the
coroutine frame and splitting the coroutine, other methods may be added
later.
* CoroSplit invokes a generator lambda to instantiate the ABI object and
calls the ABI object to carry out its primary operations.
