Add a standardized benchmark command speedtest.

Browse Source 
`speedtest [threads] [hash_MiB] [time_s]`. `threads` default to system concurrency. `hash_MiB` defaults to `threads*128`. `time_s` defaults to 150.

Intended to be used with default parameters, as a stable hardware benchmark.

Example:
```
C:\dev\stockfish-master\src>stockfish.exe speedtest
Stockfish dev-20240928-nogit by the Stockfish developers (see AUTHORS file)
info string Using 16 threads

-------------------------------

Small unrelated tweaks:
 - Network verification output is now handled as a callback.
 - TT hashfull queries allow specifying maximum entry age.
