We have a new, improved string type coming up in AK (OOM aware, no null

Making the old one have an annoying name will hopefully also help with
quick adoption :^)
This adds a new view mode to profiler which displays source lines and
samples that occured at those lines. This view can be opened via the

/usr/src/serenity/Kernel to be visible in this mode.
Currently *all* files contributing to the selected function are loaded
completely which could be a lot of data when dealing with lots of
inlined code.
