Reformat driver arguments (#12954)

* Moved top-level arguments into a single clump, rather than interlacing them with other argument groups.

* Re-formatted string literals to use single quotes rather than double in order to remain consistent in style throughout the build_swift module.

* Moved all argument help messages to the last kwarg position to remain consistent and more readable.

* Re-ordered arguments when adding a new option to always have the option strings first and then the action (if applicable).

* Re-arranged kwarg order when creating new parser options to remain consistent.

* Fixed the --enable-tsan-runtime option, which was modified recently.
