[M149] [WebXR] Check buffer detachment in XRFrame::fillPoses
Original change's description:
> [WebXR] Check buffer detachment in XRFrame::fillPoses
>
> During XRFrame::fillPoses, calling XRSpace::getPose() can synchronously
> execute script event handlers (e.g., reset events). This script may
> detach the passed-in Float32Array transforms buffer. This change validates
> that the array buffer is not detached prior to writing pose matrices.
