ci: clear out space on centos job
Clear out space on the centos job be deleteing unnecessary files.
Raised by #33293 which pointed to a solution like https://github.com/google/oss-fuzz/commit/b7f04d782277638a67bc44865de445977eed4708
Only runs when cache provider (runner) is `gha`, and on the CentOS job.
What changed, and why it matters
This commit adds a GitHub Actions cleanup step that deletes large pre-installed software folders (like .NET, Android SDK, Node modules) on CentOS CI runners to free disk space. It only affects Bitcoin Core's own continuous integration environment and does not change any Bitcoin node code, wallet logic, or network behavior. There is no security issue in the change itself.
No security action needed. Reviewers may want to confirm the deleted paths are still safe to remove on current GitHub-hosted runner images and that the backgrounded `rm -rf` does not race with later build steps.
Security signals we found
No strong security signals were identified.
Evidence from the diff
A new composite action .github/actions/clear-files/action.yml runs rm -rf against several GitHub-hosted runner directories (/usr/share/dotnet/, /usr/local/graalvm/, /usr/local/.ghcup/, /usr/local/share/powershell, /usr/local/share/chromium, /usr/local/lib/android, /usr/local/lib/node_modules) with low I/O and CPU priority. The action is invoked in .github/workflows/ci.yml only when the CI cache provider is gha (GitHub Actions). The command is backgrounded and errexit is disabled, so failures are non-fatal. This is purely a CI maintenance change to avoid out-of-space errors during the CentOS job.
