refactor: Worker is not a Future (#7895)

This commit rewrites deno::Worker to not implement Future
trait.

Instead there are two separate methods:
- Worker::poll_event_loop() - does single tick of event loop
- Worker::run_event_loop() - runs event loop to completion

Additionally some cleanup to Worker's field visibility was done.
