Summary [MSE] notifyTimeReachedAndStall must not arm a stall behind currentTime

Under some circumstances imported/w3c/web-platform-tests/media-source/mediasource-duration.html will remove content from the sourceBuffer prior the currentTime and then change the duration. MediaPlayerPrivateMediaSourceAVFObjC::resetStallForTime always assumes that the duration() is ahead of currentTime and notifyTimeReachedAndStall This set the AudioVideoRendererRemote::m_stallCap which returns std::min(currentTime(), m_stallCap) This makes the currentTime appears to jump backward with no seek
