Add skeleton code for Almanac Interfaces to have real transactions

Summary:
Depends on D19322. Ref T13120. Ref T12414.

Currently, AlmanacDevice has a bit of a beast of a TYPE_INTERFACE transaction that fully creates a complex Interface object. This isn't very flexible or consistent, and Interfaces are complex enough to reasonably have their own object behaviors (for example, they have their own PHIDs).

The complexity of this transaction makes modularizing AlmanacDevice transactions tricky. To simplify this, move Interface toward having its own set of normal transactions.

This change just adds some reasonable-looking transactions; it doesn't actually hook them up in the UI or make them reachable. I'll test that they actually work as I swap the UI over.

We may also have some code using the TYPE_INTERFACE transaction in Phacility support stuff, so that may need to wait a week to actually phase out.

Test Plan: Ran bin/storage upgrade and arc liberate. This code isn't reachable yet.
