drm/panfrost: Add fdinfo support for memory stats
A new DRM GEM object function is added so that drm_show_memory_stats can
provide more accurate memory usage numbers.
Ideally, in panfrost_gem_status, the BO's purgeable flag would be checked
after locking the driver's shrinker mutex, but drm_show_memory_stats takes
over the drm file's object handle database spinlock, so there's potential
for a race condition here.
