drm/amdgpu: Use drm_print_memory_stats helper from fdinfo

Browse Source 
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:
