fix(bench): explicit timers don't force high precision measurements (#20272) 
Disables `BenchContext::start()` and `BenchContext::end()` for low
precision benchmarks (less than 0.01s per iteration). Prints a warning
when they are used in such benchmarks, suggesting to remove them.

```ts
Deno.bench("noop", { group: "noops" }, () => {});

Deno.bench("noop with start/end", { group: "noops" }, (b) => {
  b.start();
  b.end();
});
```

Warning start() and end() calls in "noop with start and end" are ignored because it averages less than 0.01s per iteration. Remove them for better results.

summary
  noop
   2.57x faster than noop with start and end
