Graduate overlay_analysis_match_codeql_version and remove the overlay_analysis_match_codeql_version_dry_run dry run, along with the telemetry diagnostic added for it. Also, as a small optimisation, skip listing the Actions cache when only one default CodeQL version is enabled, since there is only one CodeQL version to choose in this case. This includes GHES, since there are no feature flags and therefore only one CodeQL version will ever be enabled there.
