tools: acrn-crashlog: implementation for debugger 

This patch is the implementation patch for debugger.

Debugger is the extra feature of usercrash tool. It could be run
without server in command line "debugger pid" to debug the running
process. It will dump the process info on the screen, and also the
info could be reloacted to a file.
