Add persistentFeature application attribute.

This allows us to only mark processes as persistent
when a feature it actually depends on is present on
the device.

Also adds a "android.hardware.nfc.any" feature, to
indicate the device supports any of the NFC features
that require the NFC process to run persistently.
