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.
