Refactor toolchain packaging process by introducing package-toolchain.sh

- Replaced the packaging logic in build-toolchain.sh with a call to the new package-toolchain.sh script for better organization and maintainability.
- Added package-toolchain.sh to handle the stripping and archiving of the toolchain, including necessary checks for the installation directory and environment script.
- Updated README.md to document the addition of package-toolchain.sh for clarity on the build process.
