Implement getUsdCapabilities, cancelUsdPublish, and
cancelUsdSubscribe in the mainline supplicant.

These are the simplest to implement, so they
serve as a good test case for whether the
USD dependencies are imported correctly.

Note that the implementation is copied
directly from the existing version in
the vendor supplicant.
