Description

Currently each alert is written directly to Packet::alerts during rule evaluation. Then at the end of the detection run for a packet, PacketAlertFinalize removes entries again, when applying thresholding, suppression and noalert. This leads to the issue in #4941 but is often also not very efficient esp when there are multiple rules to remove.

The idea of this ticket is to use a per DetectEngineThreadCtx specific queue of some sort to store the alert "candidates" and have PacketAlertFinalize only write the final alerts to the Packet structure.
