habanalabs: add uapi to retrieve engines status
Currently, to get engines status, user needed to read debugfs file
with root permissions.
This new uapi allows user apace apps retrieve status, so for example,
in case of failure, status can be retrieved immediately by the
application itself which runs without root permissions.
