* Remove packaged release patches
Removes the following patches:
1. The packaged installs do not support `az component` so we patch this module with appropriate messages.
2. The CLI has a feature that checks PyPI for a command module if it's not installed and the user attempts to run it. This patch disables this as components cannot be installed in packaged installs.
* Fix style
1. Adopt build stage feature. Separate the build process into build,
verify and publish stages.
2. Move build utilties from scripts folder to its own tools folder for
better organization.
3. Publish wheel artifacts to a blob storage container for long-term
persistence.
