drm: Add common fdinfo helper
Handle a bit of the boiler-plate in a single case, and make it easier to
add some core tracked stats. This also ensures consistent behavior
across drivers for standardised fields.
v2: Update drm-usage-stats.rst, 64b client-id, rename drm_show_fdinfo
v3: Rebase on drm-misc-next
