This commit fixes a panic when a host function defined with
Func::newreturned GC references and was called in async mode. The logic to auto-gc before the return values go to wasm asserted that a synchronous GC was possible but the context this function is called in could be either async or sync. The fix applied in this commit is to remove the auto-gc. This means that hosts will need to explicitly GC in these situations until auto-gc is re-added back to Wasmtime.cc #8433 as this will make the behavior consistent, but we'll want to re-add the gc behavior.
