feat: enable WebAssembly.instantiateStreaming and wasm async compilation (#11200)
The WebAssembly streaming APIs used to be enabled, but used to take
buffer sources as their first argument (see #6154 and #7259). This
change re-enables them, requiring a Promise<Response> instead, as well as
enabling asynchronous compilation of WebAssembly modules.
