tools:acrn-crashlog: Detect and classify the crash in ACRN and kernel

Browse Source 
Since ACRN has the capability to reboot and reboot reason is available
in SOS, acrnprobe could detect the crash of acrn and SOS kernel.

List of added crash types:

1. ACRNCRASH            - crashed in hypervisor, this detection depends on
                          files in /tmp/acrnlog_last(provided by acrnlog).
2. IPANIC               - crashed in SOS kernel, this detection depends on
                          pstore.
3. SWWDT_IPANIC         - crashed in SOS kernel and reboot reason is wdt.
4. HWWDT_UNHANDLE       - only recognize reboot reason is global, there is no
                          further clues that it's a SOS kernel crash or a
                          hypervisor crash.
5. SWWDT_UNHANDLE       - only recognize reboot reason is wdt, there is no
                          further clues that it's a SOS kernel crash or a
                          hypervisor crash.
6. UNKNOWN              - only recognize reboot reason is warm, there is no
                          further clues that it's a SOS kernel crash or a
                          hypervisor crash.
