[dart2wasm] Enable specific binaryen features and not blindly enable all features

We should not blindly use `--all-features` as that will tell
binaryen that it may use any features in the resulting wasm file
(even features not even finalized yet).

The default dart2wasm (without extra opt-in by the user into more
wasm features) should only enable wasm features that we require
and are available in browsers at the point when they shipped
WasmGC.
