refactor: new optimized op-layer using serde_v8 (#9843)

- Improves op performance.
- Handle op-metadata (errors, promise IDs) explicitly in the op-layer vs
  per op-encoding (aka: out-of-payload).
- Remove shared queue & custom "asyncHandlers", all async values are
  returned in batches via js_recv_cb.
- The op-layer should be thought of as simple function calls with little
  indirection or translation besides the conceptually straightforward
  serde_v8 bijections.
- Preserve concepts of json/bin/min as semantic groups of their
  inputs/outputs instead of their op-encoding strategy, preserving these
  groups will also facilitate partial transitions over to v8 Fast API for the
  "min" and "bin" groups
