cxl/memdev: Only show sanitize sysfs files when supported
If the device does not support Sanitize or Secure Erase commands,
hide the respective sysfs interfaces such that the operation can
never be attempted.
In order to be generic, keep track of the enabled security commands
found in the CEL - the driver does not support Security Passthrough.
