Add all packages with Cargo.toml's to the workspace

The primary reason for this is so that Dependabot will auto-detect them and
watch their dependencies for upgrades and known security vulnerabilities, but will
also automatically run all tests for the workspace packages with 'cargo test' without
remembering to include '--all', and build each package with 'cargo build'. I've
included 'test-data' here mostly because we want all dependencies inter-consistent
when possible even for test data/code, even if that means 'test-data' gets built
during 'cargo build --release'.
