drm/print: Add drm_coredump_printer_is_full
Add drm_coredump_printer_is_full which indicates if a drm printer's
output is full. Useful to short circuit coredump printing once printer's
output is full.
v2:
- s/drm_printer_is_full/drm_coredump_printer_is_full (Jani)
v3:
- Bail if not a coredump printer (Michal)
