Delete each version directory individually so that a symlinked one is skipped rather than removed, take an `ActionState` so the environment is read through `ReadOnlyEnv` rather than the deprecated `getOptionalEnvVar`, let `deleteToolcacheBundles` report its own failure to locate the toolcache instead of having the caller catch it, quote paths in log messages, and rename `HAS_OBTAINED_CODEQL_TOOLS` to `HAS_SET_UP_CODEQL`, which is also set when we find the tools in the toolcache rather than downloading them.

Some runner images keep the toolcache on a different volume to the workspace, so deleting the tools there frees up disk space that the analysis cannot use, and costs a later step that wanted them in the toolcache a download. Windows runners are laid out this way, with the toolcache on `C:` and the workspace on `D:`.

Run the cleanup even when the download will not be cached in the toolcache, since the toolcache shares a filesystem with the directory we extract to, so freeing it helps either way, and report an error other than the toolcache being absent as a failure rather than as an empty toolcache.

When we download a bundle the toolcache often already holds a different one that the job will not use, and on GitHub-hosted runners it shares a filesystem with the workspace, so it takes space away from the analysis. Empty the toolcache before downloading, which also frees space for the archive during extraction, and which is safe because getting as far as a download means the tools were not resolved from the toolcache. Skip this once a step has obtained the tools, since a later step may run a path it was given, and gate it on the runner being GitHub-hosted and on a feature flag that is off by default.

Recognize the linux/arm64 platform so the CodeQL CLI is accepted on
Arm64 Linux runners and the native per-platform bundle
codeql-bundle-linux-arm64.tar.zst is resolved, rather than falling
through to the combined all-platforms gzip fallback (which deliberately
omits arm64).
Add ["linux", "arm64"] to the supported platforms and make the linux
bundle name arch-aware. Keep the download mock faithful and cover the
new arch branch with tests.
