Support Per-Origin Provisioning

Browse Source 
This is a merge of several Widevine-side commits that, cumulatively,
allow callers to specify an origin to be used to isolate data storage
as specified in the W3C Encrypted Media Extension specification.
Separate origins have separate certificates, and consequently cannot
share device identifiers with each other.

The changes included in this are:

Add Ability to Check for Existing Certificates
    http://go/wvgerrit/13974
Add Ability to Remove the Certificate
    http://go/wvgerrit/13975
Make CDM Origin-Aware
    http://go/wvgerrit/13977
Add Per-Origin Storage to Widevine CDM on Android
    http://go/wvgerrit/14026
Remove Automatic Origin Generation
    http://go/wvgerrit/14031
