[CI] Auto Format Checking and test checking.

[LeiWang1999]

This pull request includes a variety of changes across multiple files, primarily focusing on improving the installation process, refining testing procedures, and enhancing error handling. The changes also include the introduction of a new continuous integration workflow and modifications to the codebase for better compatibility with different branches.

Here are the most significant changes:

Continuous Integration:

• .github/workflows/ci.yml: Introduced a new continuous integration workflow that triggers on push and pull request events. It sets up a Python environment, installs dependencies, and runs tests on a self-hosted runner.

Installation Improvements:

• install.sh, maint/scripts/installation.sh: Updated the scripts to install LLVM by fetching the appropriate version based on the Ubuntu version. The scripts now also handle different architectures (x86_64 and aarch64). [1] [2]

Compatibility Enhancements:

• format.sh: Updated the script to determine the base branch dynamically, which allows it to work with different branch names (e.g., origin/main or main). This change was applied to the format_changed(), spell_check_changed(), and lint_changed() functions. [1] [2] [3]

Other Changes:

• setup.py: Several changes were made to this file, including updating the package directory, removing the creation of a softlink for bitblas, and adjusting the versioning mechanism. [1] [2] [3] [4] [5]
• requirements-dev.txt: Added wheel and setuptools to the list of development dependencies.

CI will automatically run the format.sh once a pull request be created.

To do test locally, please run pytest in testing/python directory.
