Fixes #21660 Adds a basic `Immediate` class to mirror `NodeJS.Immediate`, and changes `setImmediate` and `clearImmediate` to return and accept (respectively) `Immediate` objects. Note that for now {ref,unref,hasRef} are effectively stubs, as deno_core doesn't really natively support immediates (they're currently modeled as timers with delay of 0). Eventually we probably want to actually implement these properly.
