[DriverFramework] Add support for querying power capabilities.

This change defines device power states and adds support for
drivers to publish their power states while adding devices.
At times, the device needs to initialize completely to publish
the device power states. In a future changeset, DdkMakeVisible
will be modified to publish the power states in those cases.

Test: Automated tests with test driver that adds second child device
to tests various cases of DdkAdd. runtests -t ddk-power-test.
