Zhaoming Jiang 6663a97b74 Dawn: Deprecate DiscoverAdapters with DiscoverPhysicalDevices
This CL deprecate Discover[Default]Adapters and replace them with
Discover[Default]PhysicalDevices. This help clearify the behavior of
discovering physical devices and requesting / getting adapters, and
prepare for adding adapter toggles in GetAdapters.

Related end-to-end tests AdapterDiscoveryTests are split into
PhysicalDeviceDiscoveryTests and AdapterCreationTests as well.
