Add Bitmap::PrevFreeRange and RangeTracker::PrevFreeRange to scan free ranges in reverse. Use PrevFreeRange during adaptive release to scan from back to front directly, avoiding candidate buffering and flattening control flow. Legacy behavior is preserved behind TCMALLOC_INTERNAL_LEGACY_LOCKING. PiperOrigin-RevId: 973934966
