Merge and improve sage's benchmarking frameworks

[mezzarobba]

Some experimental work I started a while ago and have no time to continue right now.

Overall goal: make it easy both to benchmark sage against other tools and to track the performance of various subsystems across versions.

More or less done:

• Merge the various existing bits of benchmarking infrastructure.
• Port existing benchmarks to the unified framework.
  Todo:
• Support creating benchmark suites.
• Support saving the results of a run (to compare several versions of sage or test the performance impact of a patch).
• Clean up and improve the existing benchmarks.
• ...

Component: performance

see also #25262 for using an external tool (asv) instead.

Yes, that's certainly a better option, and the attached branch has bitrotten. I think we can close this ticket. (Opinions?)

Since you created the ticket I think if you're good with closing it then it can be closed. Closing as stale.
