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.
