Re-introduce kdump debugger container cloudbuild
kdump_debugger container builds take over 1 hr on cloudbuild and often
stalled builds for other containers in automated CI. For this reason,
the automated builds for kdump were discontinued.
This change brings back time to under 10 minutes, by not building the
crash utility from source.
1. Install crash using apt-get.
2. Change ubuntu from focal to impish to capture latest crash version
3. re-introduce cloudbuild config with qemu6+ for multi-arch support
