Remove unnecessary (and incorrect) code for compatibility with Paper …
…in the Fabric version of GlobalResponderHandler (#26290) ## Summary I'm working on a refactor of the definition of `Instance` in Fabric and I came across this code that seemed to be for compatibility with Paper, but that it would actually throw an error in that case. In Paper, `stateNode` is an instance of `ReactNativeFiberHostComponent`, which doesn't have a `canonical` field. We try to access nested properties in that field in a couple of places here, which would throw a type error (cannot read property `_nativeTag` of `undefined`) if we actually happened to pass a reference to a Paper state node. In this line: ```javascript const isFabric = !!( fromOrToStateNode && fromOrToStateNode.canonical._internalInstanceHandle ); ``` If it wasn't Fabric, `fromOrToStateNode.canonical` would be undefined, and we don't check for that before accessing `fromOrToStateNode.canonical._internalInstanceHandle`. This means that we actually never use this logic in Paper or we would've seen the error. ## How did you test this change? Existing tests. DiffTrain build for [06460b6](06460b6)
