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
