Add pointers to more advanced profiling tools

We currently have a brief mention of `viztracer` in the profiling introduction, plus a link to `scalene` in the profiling conclusions. Maybe it would be useful to add a longer list of further profiling tools in the profiling conclusions. This could include [`memray`](https://github.com/bloomberg/memray), the upcoming [`profiling.sampling`](https://docs.python.org/3.15/library/profiling.sampling.html) module in Python 3.15 and probably a few others.
