Add firefox linux binaries for rust_wasm_bindgen_test (#3320)

The firefox binaries are only available for linux since there is no easy
way to extract a `.dmg` for macos and the `.exe` that firefox
distributes for the relevant platforms.

Additionally, the `@rules_rust_wasm_bindgen//:test_browser` setting
moved to `@rules_rust_wasm_bindgen//settings:test_browser`
