Resolving symlinks for file breakpoints

[michaeleisel]

It appears that, in VSCode's builtin debugger, it resolves symlinks for file breakpoints when it decides which file to open showing that the breakpoint was hit. So if I import a header, foo/bar.h which is a symlink to bar.h, and I set a breakpoint in either one, it always moves focus to bar.h when the breakpoint is hit. This would be very helpful in my case (I'm a user of Buck2, which makes lots of header symlinks that I don't want to actually edit while I mess with the breakpoint, I want to edit the original file).
