chore: optimize debian-dev Dockerfiles for better layer caching

- Separate build dependencies, brotli build, and apisix installation
  into distinct layers for improved caching
- Copy dependency files (Makefile, rockspec, .requirements) before
  source code to cache deps layer on code changes
- Remove duplicate apt-get installations in production stage
