perf(rule-engine, eventsource): Implement more efficient event bitsets

[rabbitstack]

What is the purpose of this PR / why it is needed?

For testing if the specific event bit is set, we use the map-backed bitmask. The event identifiers are expressed as an unsigned 64-bit integer. The collection of multiple bitsets permits checking whether the event type, event ID, or category bits are set. As an additional improvement, all known event IDs are put inside the mask and checked at the very early stage of event processing, dropping all uninterested or unknown event types and preventing unnecessary memory allocations.
