This PR adds support for `onMarkerProgress` (`onTransitionProgress(transitionName: string, markerName: string, startTime: number, currentTime: number, pending: Array<{name: null | string}>)`)
We call this callback when:
* When **a child suspense boundary of the marker commits in a fallback state**. Only the suspense boundaries that are triggered and commit in a fallback state when the transition first occurs (and all subsequent suspense boundaries in the initial suspense boundary's subtree) are considered a part of the transition
* **A child suspense boundary of the marker resolves**
When we call `onMarkerProgress`, we call the function with a `pending` array. This array contains the names of the transition's suspense boundaries that are still in a fallback state
