Chirantan Ekbote f1ce859903 cros_async: Refactor executors
There are a lot of changes in this one but these are the high-level
points:

* Both executors now support non-fd futures and it's now possible to
  start a poll operation on one thread and then await the result inside
  a UringExecutor on another thread.  The reverse doesn't work yet but
  will once we make UringContext sync.
* A few layers of indirection have been removed so hopefully both the
  implementation and the interface are simpler.
* The thread local magic is gone in favor of directly calling methods on
  an executor.  Executor handles can be cheaply cloned to make this
  easier.
* Heap allocations are limited to the spawn and spawn_local methods so
  it's possible to completely avoid heap allocations if callers only use
  the run_until method.
* The IoSource, Executor, FutureList traits are gone.
