wasm-builder: Enable all features when running cargo metadata (#10716)

This is required for projects like Cumulus that have dependencies on `westend-runtime`, but this
runtime is only added when the `runtime-benchmarks` feature is enabled. By having all features
"enabled" in `cargo metadata` we ensure that all crates can be found.
