* Specify extra runtime flags in tests, not CI

This enables keeping runtime/wasmtime flags scoped to just one test
rather than requiring it for all tests. For example
`-Wcomponent-model-threading` is scoped to just one test right now.

* Fix merge conflict

* Try to fix go tests

This commit fixes async import emissions in the case of lowered args
and lifted resutls.

There were a few bugs to fix:

- AsyncTaskReturn was not being emitted

- Implementation for async imports was not present

* more fixed size implementation

* more fixed list implementation

* test passes with modified wasmtime

* document and compare test

* returning a fixed size list works

* re-enable normal parameters

* clean up and use wac fork

* another testcase passing

* oh, two failing tests

* integrate changes from symmetric branch

* adapt and simplify C++ example

* modernize code

* linear code size for fixed size arrays (except when flattened)

* fix element offset, missing code for c++, missing testing argument

* leverage #1497 (wasmtime flags in test case)

* standardize on fixed *length* lists name

* another naming correction

* standardize on iter_elem variable name

* one file was missing in the last commit
