Allow Secure Stops to be queried and deleted by application ID

This CL changes the WVDrmPlugin so that an application can segregate
its secure stops from those of other applications by setting an
application ID.

This CL is a merge of the following Widevine CLs:
https://widevine-internal-review.googlesource.com/#/c/11565/
Add getSecureStop by ssid

https://widevine-internal-review.googlesource.com/#/c/11572
Add getSecureStop by SSID and releaseAllSecureStops by app id.

https://widevine-internal-review.googlesource.com/#/c/11564/
Store Usage Info by App Id (device_file stubs)

https://widevine-internal-review.googlesource.com/#/c/11563/
Add application id to StoreUsageInfo.

https://widevine-internal-review.googlesource.com/#/c/11561/
Added Application ID to PropertySet for secure stop.
