    Fix tick race in radix fault-injection scripts

    Guard any `OP_SET_INJECT_WORD`+`OP_WRITE` with 2 new functions `OP_ENGINE_TICK_ENABLE`/`OP_ENGINE_TICK_DISABLE` that enable/disable ticking in the QUIC engine. Otherwise, the radix test interpreter can tick between the 2 ops and cause the peer to close the connection prematurely
