let constructor is legacy (do not use in tree!) since the tableGen
backend emits most of the glue logic to build a pass.

Note: The following constructor has been retired:

```cpp
std::unique_ptr<Pass> createAsyncParallelForPass(bool asyncDispatch,
                                                 int32_t numWorkerThreads,
                                                 int32_t minTaskSize);
```

To update your codebase, replace it with the new options-based API:

```cpp
AsyncParallelForPassOptions options{/*asyncDispatch=*/, /*numWorkerThreads=*/, /*minTaskSize=*/};
createAsyncParallelForPass(options);
```

This doesn't flip the switch for prefix generation yet, that'll be
done in a followup.

The patch introduces the required changes to update the pass declarations and definitions to use the new autogenerated files and allow dropping the old infrastructure.

The last remaining operations in the standard dialect all revolve around
FuncOp/function related constructs. This patch simply handles the initial
renaming (which by itself is already huge), but there are a large number
of cleanups unlocked/necessary afterwards:

* Removing a bunch of unnecessary dependencies on Func
* Cleaning up the From/ToStandard conversion passes
* Preparing for the move of FuncOp to the Func dialect

Depends On D104998

Function calls "transfer ownership" to the callee and it puts additional constraints on the reference counting optimization pass
