Add support to release Linux aarch64 wheels

Problem
---------
On aarch64, ‘pip install mssql-cli’ builds the wheels from source code and then installs it. It requires the user to have a development environment installed on his system. Also, it takes more time to build the wheels than downloading and extracting the wheels from PyPi.

Resolution
-----------
On aarch64, ‘pip install mssql-cli’ should download the wheels from PyPi

@pensivebrian, Please let me know your interest in releasing aarch64 wheels. I can help with this.

Start by reproducing `pip install mssql-cli` on a Linux aarch64 system and inspect how the package currently builds and publishes wheels. Done means that the command downloads and installs a compatible aarch64 wheel from PyPI instead of requiring local build tools; the issue does not name specific files or tests.
