[Capture] add eval_jaxpr method to device api

[albi3ro]

Context:

Now that we can capture a variety of programs into hybrid quantum-classical pennylane-variant jaxpr, we want to develop a new execution pipeline for natively executing it.

Description of the Change:

Adds a eval_jaxpr method to the device interface.

Benefits:

We start making devices natively execute jaxpr.

Possible Drawbacks:

Still figuring out exactly what that workflow is going to look like.
