Simplify ThreadedActionListener construction (#93184)

DaveCTurner · web-flow · commit 416bfcbaed0d · 2023-01-25T11:15:08.000Z
- There's no real need for the caller's `Logger` just in case an impossible
  situation happens - we will get enough info from the log message.

- Almost nobody uses the `forceExecution` feature, default it to
  `false`.

- Accept an `ExecutorService` rather than requiring the whole
  `ThreadPool` only to look up the executor later on.
