This a step of the implementation of the interface for key derivation drivers introduced in #5451. The goal of this issue is to refactor the existing code to derive ECC keys (#5139) to comply to the interface of the optional derive_key entry point for transparent drivers.

This is an internal refactoring with no intended behavior change, so no new tests should be necessary, but feel free to add tests if you don't think the existing coverage is sufficient.
