tools:acrn-crashlog: unify the event analyzing process in crashlog

This patch unifies the event analyzing process in the
crashlog_sender functions:
a. analyze android events in android_events.c.
b. unify the analyzing output form of vm events and crash events.
c. concentrate the event analyzing process to the same function.
