The paths changed for 18 and again for 19. Refactor and improve
the detection logic to consider this. This also should make
the code more maintainable.
The synchronization block was too coarse and kept the lock
acquired even when the hooked call continued traversing because
it skipped the chart patch trap code. This was apparently fine
on several games but caused very flaky deadlocking on iidx18
during the boot screens and even crashed iidx19 consistently
before showing the boot screen.
