Description

In order to support the AsyncScanner we need the asynchronous streaming CSV reader back (added in ARROW-11887 but reverted later).  However, it will either need to be implemented as a mirror API (so the sync and async implementations are side-by-side) or the async-API must be wrapped with RunInSerialExecutor when called synchronously.
