Simon Sapin 5f86fd1eb8 servo: Merge #19476 - Use workspace.default-members to specify default crates for cargo build (from servo:default-members); r=nox
… and 'cargo test', etc. Include Servo and its unit tests, but not Stylo because that would try to compile the style crate with incompatible feature flags: https://github.com/rust-lang/cargo/issues/4463

`workspace.default-members` was added in https://github.com/rust-lang/cargo/pull/4743. Older Cargo versions ignore it.
