ci,scripts: install LLVM before cargo tools

Reorder bootstrap and install_build_tools.sh so LLVM 19 is installed
before cargo tools. This is needed because install_cargo_tools.sh will
install starknet-native-compile which requires LLVM to build.

Safe change: LLVM installation does not depend on Rust.
