[lldb/Commands] Refactor ProcessLaunchCommandOptions to use TableGen (NFC)

This patch refactors the current implementation of
`ProcessLaunchCommandOptions` to be generated by TableGen.

The patch also renames the class to `CommandOptionsProcessLaunch` to
align better with the rest of the codebase style and moves it to
separate files.
