Expose conditional `FlowController` classes (#<I>)

In #<I>, the conditional flow-controller classes
`ConditionalController` and `DoWhileController` were promoted to being
able to be added to a `PassManager` directly via `PassManager.append`.
Since they are now a bit more public, this commit exposes them in the
`qiskit.transpiler` module (the same as `PassManager`), and adds them to
the documentation.
