perf(cli): use new deno_core timers (#22569)
Improves #19100 

Fixes #20356

Replaces #20428



Changes made in deno_core to support this:

 - [x] Errors must be handled in setTimeout callbacks
 - [x] Microtask ordering is not-quite-right
 - [x] Timer cancellation must be checked right before dispatch
 - [x] Timer sanitizer
 - [x] Move high-res timer to deno_core
 - [x] Timers need opcall tracing
