Hendiadyoin1 4c2b4c1a27 LibJS: Overhaul AsyncFunctionDriverWrapper to make it actually work ...

This object is responsible for handling async functions in bytecode,
and this commit fully rewrites it, now it does:
* creates and keeps alive a top level promise, which callers can attach
  their `then` clauses
* creates and clear a handle to itself, to assure that it does not get
  garbage collected
* properly handles all possible ways a async function could halt and
  when possible continues the execution immediately
