[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.
