    Original change's description:
    > [wasm][debug] Fix tier down during streaming compilation
    >
    > If the debugger is enabled while streaming compilation is happening, we
    > won't correctly tier down to Liftoff. This is because during streaming
    > compilation, we always compile for no debugging. Fixing that is a bit
    > tricky, since when the debugger is enabled, functions can either already
    > have finished compiling, or they are currently being compiled, or their
    > wire bytes are not received yet.
    > Instead of handling this correctly while streaming compilation is
    > running, we just recompile the whole module with Liftoff after streaming
    > compilation finished.
    >
    > For testing this, we use the existing tests for async compilation, and
    > enable --wasm-test-streaming, which compiles via the streaming decoder
    > even in the async compilation case.
