tee: add TEE_IOCTL_PARAM_ATTR_TYPE_OBJREF

The TEE subsystem allows session-based access to trusted services,
requiring a session to be established to receive a service. This
is not suitable for an environment that represents services as objects.
An object supports various operations that a client can invoke,
potentially generating a result or a new object that can be invoked
independently of the original object.

Add TEE_IOCTL_PARAM_ATTR_TYPE_OBJREF_INPUT/OUTPUT/INOUT to represent an
object. Objects may reside in either TEE or userspace. To invoke an
object in TEE, introduce a new ioctl. Use the existing SUPPL_RECV and
SUPPL_SEND to invoke an object in userspace.
