Allow provisioning model to be queried

Browse Source 
[ Merge of http://go/wvgerrit/152674 ]

This allows an app to query the provisioning model. Possible
values are { "DrmCertificate", "Keybox", "OEMCertificate",
"BootCertificateChain" }

An app can use these to disntinguish between provisioning models.
Provisioning 4.0 (boot certificate chain) requires a double provisioning
step.
