The full set of supported activation types are {'elu', 'gelu', 'leaky', 'prelu', 'rrelu', 'selu'}. What about the rest of the activation types? Will they be supported by onednn in the future?

Those were activation types that can be easily fused with FC in this PR. We plan to enable other activation fuses in the next PR as they need different approach.
