Create Configurable run_tests Bash Script and Tests Folder

Description

colcon test is not the only test that should be run on the Autoware.Auto stack. Linters and static analysis tools which don't have ament variants usually require command-line flags and configuration files. These need somewhere to live and a script which can easily run them.

Expected behavior

Running tests beyond colcon test should be easy and user-friendly.

Definition of Done

• Create a tests folder in the root of the Autoware.Auto repository
• Create a bash script with configurable options that runs all or a subset of the recommended tests
• Use this bash script in CI instead of running tests individually
