test: add common.skipIfEslintMissing

We've added a number of tests that hook into ESLint which can error when running the test suite with the distributed tarball. This PR adds a new test helper `common.skipIfEslintMissing` and will skip remaining tests in a file when `ESLint` is not available at `tools/node_modules/eslint` PR-URL: #18807 Reviewed-By: Rich Trott <[email protected]> Reviewed-By: Richard Lau <[email protected]> Reviewed-By: James M Snell <[email protected]> Reviewed-By: Yuta Hiroto <[email protected]> Reviewed-By: Colin Ihrig <[email protected]> Reviewed-By: Ruben Bridgewater <[email protected]>
