enable --enable-bulk-memory in wasm-opt by default #4186
Description
in Rust 1.87, target-feature=bulk-memory became enabled by default, but our wasm-opt pipeline does not enable it. We need to update our default config to pass it through.
This is a bit strange to me though, since we always pass target-features through.
Discussed in #4183

Somehow in the latest nixos 24.11 and 25.05 something changed, and now I am getting this error:

Any ideas?
Am using 0.2.100 of wasm-bindgen-cli, that hasn't changed. Assuming dx is correctly using the installed version still.
