common/async: remove unused common/async/bind_like.h

this re-bound the associated executor and allocator, but didn't preserve
other associations like cancellation slot or immediate executor

i don't see this used anywhere, and hope that most cases can use asio
algorithms like asio::append(), asio::consign(), etc instead
