Support for the new device API

[rmoyard]

Context:

PennyLane recently added a new device API.

Description of the Change:

In this PR we create anothe QJIT device that supports the new device API. Users define preprocessing by adding transforms to the preprocess method.

We can add our own transforms in the QJIT device preprocess function, if necessary.

Thanks @rmoyard! My main concern is around the interaction between custom Catalyst operations/restrictions, the TOML specification, and the device pre-processing.
