This commit simplifies the build script slightly for generating tests by doing a few dull refactorings: * Leaves formatting to `rustfmt` * Extract bulk of code execution into a top-level shared `run_wast` function so each test is a one-liner * Use `anyhow` for errors both in the script and in tests
