[sanitizer_common] Added VS-style output for source locations
Summary: With this patch, we have a flag to toggle displaying source locations in the regular style: file:line:column or Visual Studio style: file(line,column) This way, they get picked up on the Visual Studio output window and one can double-click them to get to that file location.
