Add an OnEveryBit Bloq?

[fdmalone]

We have OnEach which hides the splits / joins necessary to apply n single qubit gates to an n-qubit register. We could also add an OnEveryBit bloq to add a collection of single qubit gates (or maybe n-qubit gates in a more general form) to a bigger register. An example is applying a sequence of rotations which each have a different angle, which currently requires a split/join in the decomposition.

Hmm, maybe we just want something for rotations specifically, as I admit it's a bit specific, but it could also be helpful for say a tower of CNOTs.

One approach would be to implement these cases "manually" and make a note or keep a list of the places where they crop up as empirical evidence of what sort of abstractions would see widespread use

[fdmalone]

Not important.
