[dawn][emscripten] Use doubles for future ids.

- This fix is stemmed from an issue where because mapMode in
  mapAsync is a bitmask which means by default in WASM we are
  using a uint64_t to represent it. As a WASM type, this was
  a 'j' that needs to be taken as 2 args much like the future
  id. Because it was hard to find this issue hidden by the fact
  that we were manually turning __i53abi off for some shims,
  this change refactors futures to always be passed to JS
  from WASM as a uint64_t/'j' type with __i53abi as true, and
  passed from JS to WASM as a double which we can cast back.
