Add 'make lint', restructure 'compliance' pipeline (#10861)

- Added 'lint', 'lint-frontend', 'lint-backend' targets
- Added 'lint-frontend', 'lint-backend' ci steps and restructure the
  'compliance' pipeline to have a clear separation between frontend and
  backend and use parallelism where possible. Also, the main build
  pipelines now depend on 'compliance' so they will skip if it fails.
- Added dependencies on ci steps so they skip when 'compliance' fails
- Moved JS linters to devDependencies
- Removed deprecated 'js' and 'css' targets
