Disabling in flutter/engine#52713

On the drawpoints macrobenchmark app, repeatidly toggling the performance overlay causes graphical artifacts. We tried increasing the host buffer pool and removing buffer recycling and the issue persisted. This indicates that it is a potential problem on the synchronization fence when presenting.

At present, we're unsure of the correct barrier, or if we need to synchronize on the CPU (though it seems like that would defeat the purpose?).
