AudioDeviceInventory: add cache for preferred device roles

Add a cache for the last selected devices role (disabled/preferred)
for any strategy or capture preset.
This avoids redundant and frequent rerouting requests sent to audio
policy manager causing delays and glitches in audio playback and
capture.
