tests: Refactor tests script for better readability

`State` class naming was a mistake, renaming it to Options

And refactor the member functions of State into member functions of
`Base`, `Test_Implementations`, `Tests`

`Base`: the lowest level class for handling compilation and binary
execution
`Test_Implementations`: handle running one or multiple implementations
`Tests`: provide top level functions for click cli commands
