Clemens Backes 8d3cca9792 Revert "[wasm][debug] Fix tier down during streaming compilation"
This reverts commit 3cc981cb7a.

Reason for revert: TSan failures: https://ci.chromium.org/p/v8/builders/ci/V8%20Linux64%20TSAN/31572

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.
