Refactor the giant bash blob in //build:kong target to Bazel rules that each output files are tracked. So that:

• We won't accidently copy extra files if upstream projects change.
• We don't accidently overwrite files between targets (error will occur).
• Use the actual Output files lists (from foreign_cc rule or genrule as the source) truth to determine what files to install. For example, we simply don't output headers if not needed, instead of copy_with_filter when install.
• Add or modify a target to install is easier and doesn't involve bash-fu.
• Developer can use individual //build:install-xx target to only build and install selectd components, like //build:install-openresty only install openresty and openssl and skip luarocks etc.

Other noticable changes:

• Also a new //build:dev-make-openresty target is added so that developer can use it to invoke make directly for openresty development.
• Lua files and C extensions that are not installed by luarocks are now installed into PREFIX/openresty/site/lualib where typically PREFIX is /usr/local. This is to avoid collide with openresty bundled files (PREFIX/openresty/lualib), where those files used to be installed under.
• Bumps atc-router to v1.6.2:
  • chore(cargo): release v1.6.1 by @dndx in chore(cargo): release v1.6.1 atc-router#216
  • chore(build): add a new target to include lua files by @fffonion in chore(build): add a new target to include lua files atc-router#219
