Subject: feat: deno test --trace-ops (#13770)

This commit adds "--trace-ops" flag to "deno test" subcommand.

This flag enables saving of stack traces for async ops, that before were always
saved. While the feature proved to be very useful it comes with a significant performance
hit, it's caused by excessive source mapping of stack frames.
