scripts: Add POSIX setup script template

This commit adds a setup script template for the POSIX-compliant host
operating systems (i.e. Linux and macOS) to be distributed as a part of
the Zephyr SDK distribution bundle archive.

This setup script can be executed by the user to configure the Zephyr
SDK on their local system.
