[iOS] Fix hooks API not cancelling JS Responder (#4261)

## Description

Fixes
#4258

JS-responder cancellation relies on `RNRootViewGestureRecognizer` being
installed on the surface view. The legacy path installs it in
maybeBindHandler via
`registerViewWithGestureRecognizerAttachedIfNeeded`, but the hook-API
detector attached handlers straight to the registry and skipped that
step, so activation could never cancel the JS responder.

This PR adds
`attachHandlerForDetectorWithTag:toView:withActionType:withHostDetector:`
on `RNGestureHandlerManager` which handles that.

## Test plan

Tested on the issue reproducer
