Introduce microdump_stackwalk comand line executable

This introduces the microdump_stackwalk binary which takes advantage
of the MicrodumpProcessor to symbolize microdumps.
Its operation is identical to the one of minidump_stackwalk.
This CL, in fact, is also refactoring most of the common bits into
stackwalk_common.
