#16153: Add fused activations to input tensors

[patrickroberts]

Ticket

#16153

Problem description

Fused activations are not implemented with generality, but are needed for input and output tensors.

What's changed

Pipelines of unary tensor functions called "activations" can be chained onto inputs preceding the binary op via lhs_activations and rhs_activations parameters, and onto output proceeding the binary op via post_activations.

Depends on #16276
