Implement GetDeviceId for prov4

Browse Source 
[ Merge of http://go/wvgerrit/150349 ]

The device id for prov4 is hash of the encoded device public key
(COSE_key).

Also replaced a few bug numbers if it is prov3 specific (not related to prov4).

/**
* Return a device unique id. For devices with a keybox, retrieve the
* DeviceID from the Keybox. For devices that have an OEM Certificate instead
* of a keybox, it should set the device ID to a device-unique string, such
* as the device serial number. The ID should be device-unique and it should
* be stable -- i.e. it should not change across a device reboot or a system
* DeviceID from the Keybox. For devices that have an OEM Certificate, or if
* provisioning 4 is used, it should set the device ID to a device-unique
* string, such as the device serial number or a hash of the device public key
* in boot certificate chain. The ID should be device-unique and it should be
* stable -- i.e. it should not change across a device reboot or a system
* upgrade. This shall match the device id found in the core provisioning
* request message. The maximum length of the device id is 64 bytes. The
* device ID field in a keybox is 32 bytes.
