print_stats: add `cancelled` when `CANCEL_PRINT` used (#4366)

Before this change, a `CANCEL_PRINT` set a `print_stats` to `paused`
that would later be workaround-ed with `fluidd`/`mainsail` to re-define
`CANCEL_PRINT`.

This sets a proper canceled state, but additionally closes a file
from a `virtual_sdcard` context for `canceled`/`error`, as this is no longer
resumable from this point.
