Add minidump analysis python script for Windows crash dumps
This script takes a Swift version and minidump file path as arguments and will checkout the corresponding source, fetch and extract the corresponding installer, fetch and extract the corresponding debug symbols to finally run the Windows SDK command line debugger (cdb) to write a human readable stack trace and further info to a txt file. Test-Information: Tested it successfully on Windows 10 with various minidumps. Change-Id: I5915255dfb23e6b45c1273a3c1c42cc83125df57
