refactor: migrate async ops to generated wrappers (#18937)

Migrates some of existing async ops to generated wrappers introduced in
https://github.com/denoland/deno/pull/18887. As a result "core.opAsync2"
was removed.

I will follow up with more PRs that migrate all the async ops to
generated wrappers.
