fix(setup_board): Remove unused support for special amd64-host boards.

This was some scheme for building packages using the SDK profile instead
of the normal target board profiles. We use catalyst instead so remove
this dead code. Ordering cleaned up slightly as well.
fix(catalyst): Move catalyst scripts from lib to build_library.

Just seems like a better place for them.
