  [mlir][Transforms][NFC] Remove `SplitBlockRewrite`

When splitting a block during a dialect conversion, a `SplitBlockRewrite` object is stored in the dialect conversion state. This commit removes `SplitBlockRewrite`. Instead, a combination of `CreateBlockRewrite` and multiple `MoveOperationRewrite` is used.

This change simplifies the internal state of the dialect conversion and is also needed to properly support listeners.

`RewriteBase::splitBlock` is now no longer virtual. All necessary information for committing/rolling back a split block rewrite can be deduced from `Listener::notifyBlockInserted` and `Listener::notifyOperationInserted` (which is also called when moving an operation).
