drm/v3d: Expose memory stats through fdinfo
Use the common DRM function `drm_show_memory_stats()` to expose standard
fdinfo memory stats.
V3D exposes global GPU memory stats through debugfs. Those stats will be
preserved while the DRM subsystem doesn't have a standard solution to
expose global GPU stats.
