drm/xe/debugfs: Add interface to trigger power management unit error handler

Add a debugfs interface to manually trigger power management unit error
handler for testing cold reset recovery paths. This is useful for
validating the error recovery mechanism.

The new debugfs entry 'trigger_punit_error' is located at:
/sys/kernel/debug/dri/N/trigger_punit_error

Reading the file displays usage instructions. Writing '1' invokes
xe_punit_error_handler(), which marks the device as wedged with
DRM_WEDGE_RECOVERY_COLD_RESET method and sends a uevent to userspace
indicating that a complete device power cycle is required for recovery.

Writing '0' or any other false value has no effect.

This interface is intended for development, testing, and validation
of power management unit error recovery code.
