ci: port CentOS Stream test to GitHub Actions using Lima

Move the CentOS Stream 9 based test from Cirrus CI to GitHub
Actions using Lima VMs. Expand coverage to a matrix of CentOS
Stream 9 and 10 on x86_64.

Consolidate lima-fedora-rawhide.sh and the new CentOS Stream
logic into a single scripts/ci/lima.sh with distinct function
names (fedora-rawhide-setup/test, centos-stream-setup/test).

Extract the common Lima VM setup steps (Lima install, image
caching, KVM enablement, VM start, source copy) into a reusable
composite action at .github/actions/lima-vm-setup.
