ao_wasapi: Refactor device listing/loading

Omit "{0.0.0.00000000}." on devices that start with that substring,
re-add when searching for devices by ID.

Log the device ID of the default device.

Log the friendly name of the used device.

Consistently refer to endpoints/devices as devices, as this is more
consistent with mpv terminology.
