Log:
c++-coroutines - Address review comments, rework identifiers.

There are quite a lot of identifiers for coroutines; including the main
ones for the trait etc. and those for the promise methods and awaitables.

We decided to make these local to the coroutines implementation and to
initialize them lazily on the first coroutine encountered.
