[mlir] Move SelectOp from Standard to Arithmetic

[rriddle]

Summary

This is part of splitting up the standard dialect. See https://llvm.discourse.group/t/standard-dialect-the-final-chapter/ for discussion.

[lattner]

Nice, this is a clearly good step forward to me.

 The code, slightly simplified and annotated, is reproduced here:
 
 ```c++
   // Partial bufferization passes.
   pm.addPass(createTensorConstantBufferizePass());
   pm.addNestedPass<FuncOp>(createTCPBufferizePass()); // Bufferizes the downstream `tcp` dialect.
   pm.addNestedPass<FuncOp>(createSCFBufferizePass());
   pm.addNestedPass<FuncOp>(createLinalgBufferizePass());
-  pm.addNestedPass<FuncOp>(createStdBufferizePass());
   pm.addNestedPass<FuncOp>(createTensorBufferizePass());
   pm.addPass(createFuncBufferizePass());
 
   // Finalizing bufferization pass.
   pm.addNestedPass<FuncOp>(createFinalizingBufferizePass());
 ```
 
 Looking first at the partial bufferization passes, we see that there are a
