This PR include two changes: 1. Change debuginfod cache file name to include origin file name, the new file name would be something like: llvmcache-13267c5f5d2e3df472c133c8efa45fb3331ef1ea-liblzma.so.5.2.2.debuginfo.dwp So it will provide more information in image list instead of a plain llvmcache-123 2. Switch debuginfod cache to use lldb index cache settings. Currently we don't have proper settings for setting the cache path or the cache expiration time for debuginfod cache. We want to use the lldb index cache settings, as they make sense to be in the same place and have the same TTL. --------- Co-authored-by: George Hu <georgehuyubo@gmail.com>
