There was a problem hiding this comment.
Seems the spec discussion is ongoing but lgtm to land this if it helps investigation for the spec.

Oh, I would fuzz this before landing. I wouldn't be surprised if the fuzzer can do something surprising with the new testcase here - may need to disallow it. |
Also change unreachable message

Will fuzz before merging and add a validator rule disallowing WaitQueue fields unless shared everything threads is enabled in the next PR. |

Ran the fuzzer for 9000 iterations with no errors. It hit an error at the end but it was due to a stack overflow from a Wasm binary with a deep call stack and succeeded after I increased my stack size (and was the same from main as my branch). |

Part of #8315. Adds initial binary + text parsing and printing for the packed waitqueue type.
Beyond the rest of the functionality, we also need to add validator rules that waitqueue can only be used when shared everything threads is enabled. Will add that in the next PR.
