feat(packaging): add voxl2 Debian package build

Add make_package.sh and supporting files to build a .deb package
for the voxl2 target, bundling both the ARM64 apps processor binary
and Hexagon SLPI DSP library. The package version is derived from
the git tag and short commit hash. CI is updated to build and upload
the .deb alongside existing .px4 artifacts.
