Move Linux arm64 CI from dead Cirrus CI to ubuntu-24.04-arm

Cirrus CI stopped reporting check runs on develop sometime after
d10879bca (2026-05-26); every commit since has only github-actions
check runs, so .cirrus.yml silently lost its only consumer while
README.md, FILES.md and the QA page kept advertising the coverage.

Add a ci_test_arm64 job to ubuntu.yml using the same pinned
actions/checkout and lukka/get-cmake actions as the other jobs, on the
native ubuntu-24.04-arm runner, with a step that confirms uname -m
reports aarch64. Delete .cirrus.yml and its README badge and FILES.md
section, and update the QA page's arm64 row.

Part of #5715
