Add pointers to more advanced profiling tools

[JostMigenda]

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, the upcoming profiling.sampling module in Python 3.15 and probably a few others.

Sounds good. Though I'd probably be tempted to overtime migrate guidance to profiler.sampling, e.g. as it should be much nicer for line profiling than line_profiler.
