Convert fdinfo memory stats to use the common drm_print_memory_stats helper. This achieves alignment with the common keys as documented in drm-usage-stats.rst, adding specifically drm-total- key the driver was missing until now. Additionally I made the code stop skipping total size for objects which currently do not have a backing store, and I added resident, active and purgeable reporting. Legacy keys have been preserved, with the outlook of only potentially removing only the drm-memory- when the time gets right. The example output now looks like this: pos: 0 flags: 02100002 mnt_id: 24 ino: 1239 drm-driver: amdgpu drm-client-id: 4 drm-pdev: 0000:04:00.0 pasid: 32771 drm-total-cpu: 0 drm-shared-cpu: 0 drm-active-cpu: 0 drm-resident-cpu: 0 drm-purgeable-cpu: 0 drm-total-gtt: 2392 KiB drm-shared-gtt: 0 drm-active-gtt: 0 drm-resident-gtt: 2392 KiB drm-purgeable-gtt: 0 drm-total-vram: 44564 KiB drm-shared-vram: 31952 KiB drm-active-vram: 0 drm-resident-vram: 44564 KiB drm-purgeable-vram: 0 drm-memory-vram: 44564 KiB drm-memory-gtt: 2392 KiB drm-memory-cpu: 0 KiB amd-memory-visible-vram: 44564 KiB amd-evicted-vram: 0 KiB amd-evicted-visible-vram: 0 KiB amd-requested-vram: 44564 KiB amd-requested-visible-vram: 11952 KiB amd-requested-gtt: 2392 KiB drm-engine-compute: 46464671 ns v2: * Track purgeable via AMDGPU_GEM_CREATE_DISCARDABLE.
