Relax linalg elementwise fusion check to allow mixed consumers. Producer is still required to be fully tensor to avoid potential memref aliasing.

This is the second (and final) step of making "destination style" usable without depending on the Linalg dialect. (The first step was D135129.)
This change allows us to provide default bufferization implementations for all destination-style ops. It also allows us to simplify `TilingInterface`. (E.g., `getDestinationOperands` can be removed.)
