Clemens Hammacher 233cb0bfc6 [wasm][test] Remove default --wasm-async-compilation flag
The flag is on by default, so we don't need to specify it. More
importantly, the tests are expected to work for any value of that flag.
So don't force the flag but use whatever the test variant chooses.

Note that in streaming-compile.js, the flag was accidentally specified
as '-async-compilation'. I also removed that one.
