41b39c5e1f tools: acrn-crashlog: Defer the vm events processing when failed
In the original design, acrnprobe marked all handled VMs'events as "synced"
in file vmrecordid(this patch changes the name to VM_eventsID.log).
Currently, the Android log events are not logged if the first attempt at
reading collecting them from the VM fails. This patch changes the logic
so that the acrn-crashlog tool will retry continuously.

This patch defines different tags for handled VMs'events, and only marks
VMs'events "synced" after it returns successfully.
